Rocuronium bromide: a pharmacological study
This work was designed to assess the pharmacological effects of rocuronium. In either isolated preparation or intact animals. Rocuronium (6-96 μg/ml) caused a significant dose related reduction in the amplitude of rat phrenic nerve diaphragm contraction in response to indirect stimulation, the mean percentage reduction were statistically significant. The addition of neostgmine (0.25 μg/ml) caused complete reversal of the relaxant effect of rocuronium . In intact cat gastrocnemius sciatic nerve preparation rocuronium (25 - 200 μg/kg) caused dose dependent statiscally significant reduction. In comparing the drug with succinyl choline by the head drop method the mean time in second was 15.34 ±1.57 and 10.44 ±0.91 respectively.

Comparitive Study Between Cnventional and Hyperfractionaltion Radiation Therapy for The Treatment of Brain Stem Tumors
Brain stem tumors are special challenge because primarily of their location and the neurologic effect caused by these groups of tumors (Paul 1997).
Radiation therapy improves survival for brain stem tumors and stabilizes or reverses neurologic dysfunction in 75-90% of patients.
The main domain of applicability of hyperfractionation would be in tumor sites where the dose limiting tissue is late reacting and whose effective control requires the delivery of doses beyond tolerance (Awwad, 1990), hence the rationale for the use of hyperfractionation in brain stem lesions.
The purpose of this work is to find out the best radiation protocol in this group of patients comparing conventional fractionation and hyperafractionation.
This study included 46 patients which brainstem tumors treated in Radiation Oncology and Neurosurgery Departments Ain Shams University between February 1998 and May 2000.
These patients had been randomly distributed in 2 groups A and B. The first group treated by conventional radiotherapy protocol and the second group treated by hyperfractionation radiation protocol.
By the end of the study, the median over all survival and median time for disease progression were calculated for each group.
Age, neurologic status at presentation and anatomical location were significant prognostic factors.
By the end of this study clicinal evalualion had no significant difference between both groups but the median over all survival for the two groups was 10.5 months, the median survival for group A was 9.4 months and that for group B was 11.5 months which was statistically significant P < 0.02.
On the other hand the percentage of patient with one year survival for group A & B (22%, 32%) respectively.
The rate of acute (early) reaction of radiation is slightly higher in hyperfracticmaticm than conventional fractionation but the late reactions occur with same frequency with both regimens.

Incidence of Larval and Adult Mite ( Sarcoptes scabiei) Stages in Scabietic Pateints from Three Regions of Qalyobia Govern orate
Human scabies is a highly contagious infestation caused by the itch mite, Sarcoptes scabiei var. hominis. Although it is not a life threatening condition, yet it may be considered important because some cases may be complicated by post- streptococcal glomerulonephritis. Understanding of the conditions affecting the life cycle of Sarcoptes scabiei is essential for prevention of its transmission in the community. Scrapings from the affected skin were prepared from scabietic patients attending the local pharmacies for buying medicine prescribed by physicians in private clinics, or asking advice from the pharmacist, through-out the months of the year. Statistical analysis of the data revealed a high correlation between the number of patients, and the mean number of adult and larval stages of S. scabiei. In cold months, more patients, mostly children(70%) were infested by a larger number of larvae and adult mites.

Progressive effects of the interaction of Sodium nitrite and sunset yellow on different physiological parameters in albino rats
It has been noticed that the Egyptian children usually eat and drink food containing both food preservative and food colourants at the same time . This has attracted the attention to study the interaction between one of food preservatives (sodium nitrite) and a food coloring agent (sunset yellow). The mixture of the two agents at the limited dose of each was found to be a lethal dose. So, 1/10th of this dose was used daily for 30 days. Animals were devided into three groups. The first group served as a control, while the second group was orally administered a mixture of 10mg sod. nitrite (NaNO3)/kg and 0.5 mg/ kg /day sun set yellow (S.S.Y)/. The third group received selenium (5 mcg/kg) in addition to the above mentioned mixture. After 30 days of treatment, half of the animals from each group were decapitated. The other half of animals was left for another 15 days without treatment for recovery.
Ingestion of the mixture of (NaNO3 and S.S.Y) significantly decreased rat body weight, R B C and WBC counts, Hb %. , Hct %. Serum inorganic phosphorus, serum protein and serum albumin. Significant increases were observed in serum glucose, T3, T4, calcium, GGT, LDH, Cpk, ALK.ph and cholesterol. Also cholesterol of brain, liver and heart were significantly elevated. No changes were recorded for organ/ body weight, respiratory rate, heart beats, rectal temperature, AST and ALT activities of serum and tissues, acid phosphatase activity, total lipids of serum and tissues, cholesterol of muscle and kidney and serum triglycerides
A complete recovery from the abnormalities of most biochemical and haematological parameters was observed after 15 days recovery or when selenium was administered This draws attention to the dangers of interactions of such preservatives and colorants. The present study showed that even the permitted doses of colourants and food preservatives may be harmful.

Modification of controlled hypotension induced by nicardipine or nitroprusside in cats pretreated with injectable acetyl salicylic acid
Controlled hypotension is a well established technique to decrease blood loss and improve surgical visibility. Several different pharmacologic agents have been used for controlled hypotension including direct acting vasodilators such as sodium nitroprusside and calcium channel blockers (Testa and Tobias, l995) . This study was designed to assess the effect of non-steroidal anti-inflammatory drug (NSAID) acetyl salicylic acid (ASA) therapy on the efficacy and safety of I.V. infusion of nicardipine compared with the more commonly used agent; sodium nitroprusside. The effect of each drug on blood pressure and ECG pattern of normal"control" cats and cats pretreated with (ASA) was investigated. A target mean arterial pressure (MAP) of 55-65 mmHg was to be achieved. It was found that both nicardipine and nitroprusside achieved a stable controlled hypotensive state in control groups. Comparison between the two drugs revealed a significant increase in (MAP) with nitroprusside after drug discontinuation. Pretreatment with (ASA), attenuated significantly the effect of nicardipine infusion on (MAP) . However, pretreatment with ASA produced insignificant effect on the decrease in MAP caused by nitroprusside except at 4 min. during infusion where ASA pretreatment attenuated its effect. Moreover (ASA) pretreatment decreased nitroprusside dose needed to reach the target blood pressure and increased time of blood pressure to returin to base line. Both nicardipine and nitroprusside infusion caused increase in mean heart rate (HR) without ECG changes in control and pretreated groups.There was a Statistically significant increase in (HR) in the (ASA) pretreated groups of both drugs when compared to that in the control groups. When the increase in (HR) induced by nitroprusside infusion was compared to that induced by nicardipine infusion, there was
insignficiant difference in the control groups, difference was significant.
INTRODUCTION:
One of the commonly used technique to limit blood loss and the possibility of transmitting infectious diseases in orth -opedic surgical procedures is controlled hypotension. Controlled hypo -tension; referred to as delibrate or induced hypo -tension, is
while in (ASA) pretreatred groups the difference was significant.

Effect of Aqueous Extracts From Some Plants on Alloxan – Diabetic Rats.
The present study aims to clarify the effect of aqueous extracts from green tea, sage (Salvia officinalis) and ginseng panax (panax quinquefolius L.) on the insulin sensitivity in the alloxanized diabetic rats. The experiment included twenty four normal male albino rats and 24 diabetic ones. They were classified into eight groups each of 6 rats. Two groups served as control (one normal and one diabetic rats) and the other groups were orally given the doses of aqueous extract for four weeks. The chemical analysis included level of blood glucose, plasma insulin, serum total cholesterol, serum triglycerides, HDL-cholesterol and LDL- cholesterol, in addition to the influence of these aqueous extracts on the liver glycogen and various enzymes of glucose metabolism (Glucose 6-phosphatase, ALT, AST and alkaline phosphatase).
The results revealed significant decrease (p<0.05) in blood glucose, and highly significant increase in both liver glycogen content and serum insulin level in the diabetic group treated with aqueous extracts of tested plants in this study when compared with the diabetic untreated group.
Serum lipids (triglycerides, total cholesterol, LDL- cholesterol and HDL- cholesterol) and various enzymes of glucose metabolism (ALT, AST, ALP and glucose- 6-phosphatase) showed significant decrease in the diabetic group treated with aqueous extracts of tested plants when compared with the diabetic group. It is clear from the current data in this study that ginseng aqueous extract was the most efficient of the three tested plants.

Effect of Some Environmental Factors on the Predation Efficiency of the Mosquito; Toxorhynchites splendens (Diptera: Culicidae)
The present work investigates the optimum conditions for the application of the predaceous mosquito, Toxorhynchites splendens as a biological control agent for other vector mosquito species in Egypt such as, Culex pipiens, Anopheles pharoensis and Aedes caspius under field conditions.
The predation efficiency of T. splendens larvae was found to increase as the temperature increased. At 30-35؛C the predaceous larvae consumed greater numbers of both C. pipiens and Ae. Caspius than that of A. pharoensis. The predation of T. splen –
dens occurred almost similarly in all degree of salinity. On the other hand, light was found to have little effect on Toxorhynchites larvae where predation efficiency was decreased in the dark. The crowding had no effect on the predation. Also no mortality or natural diseases were observed among the tested insect larvae during the experim ental period, whereas the insect preferred to live in highly concentrated population.
Toxorhynchites splendens larvae could live in turbid and distilled water. The maximum number of prey larvae consumed by all instars of T. splendens was at PH (8) followed by (7) and (9). However, pH, below (6) and above 11 had a bad effect on the predaceous activity. The predation efficiency of T. splendens larvae increased gradually as the depth of water decreased .However captures of prey occurred either on the surface or at the bottom of the container.

COMPARATIVE HISTOLOGICAL AND CLINCAL STUDY OF TWO INHALAR ANAESTHETICS
Sevoflurane (Fluromethyl 1,1,1,3,3,3, Hexafluoro isopropyl ether) is one of the newly introduced inhalational Anaesthesia. It is considered as a rapid acting and potent inhalation anaesthetic agent. It is metabolized in the body into non-toxic substances. It also has a rapid uptake and elimination rate due to its low blood gas partition coefficient, which approaches that of nitrous oxide. Interest in sevoflurane has increased with the recent emphasis for out patient surgery because it has a mild ethereal odor and low solubility in blood; lipid; and tissues. So, it is suggested as being anaesthetic of the future. This study is designed to illustrate the histological and the clinical effects of sevoflurane in comparison with isoflurane as a common inhalational anaesthetic agent, regarding the haemodynamic, hepatic and renal effects. The clinical study included 80 adult persons of both sexes, during surgical operations. The patients were divided into 2 groups, 40 persons each. Group I: received sevoflurane and group II: received isoflurane. Routine examinations; investigations; Liver and renal function tests were done just before induction and after 2 hours; 4 hours; 24 hours and 7 days of recovery. The experimental study was done on 90 rats of both sexes. They were divided into 3 groups: 30 rats each. Group (A): control group, group (B): Anaesthetized with sevoflurane and group (C): Anaesthetized with isoflurane. Each group was subdivided into 2 subgroups, 15 rats. The 1st subgroup was sacrificed after 24 hours of exposure. The 2nd subgroup was sacrificed after 7 days from the start of exposure. The rats were sacrificed and their blood was investigated. Liver and kidney structure were evaluated histologically and histochemically. Our results revealed that, sevoflurane and isoflurane had non-significant post-operative clinical manifestations and non-significant changes on the liver or kidney function tests. Histological examination of liver revealed normal hepatocytes and mild congestion in blood sinusoids and central veins in sevoflurane group. While, liver sections in isoflurane group showed more congestion, dilatation and cellular infiltration. . Histological examination of the kidney revealed no changes in the sevoflurane group. In contrast, isoflurane group had congestion and cellular infiltration of renal parenchyma. All changes almost completely disappeared after seven days of recovery. Histochemical results revealed significant decrease in PAS positive material and succinic dehydrogenase enzyme activity in hepatocytes and renal tubules, mainly in isoflurane than sevoflurane groups. While, acid and alkaline phosphatase enzymes activity showed non-significant decrease in both drugs. All changes were non- significant after seven days of recovery. This study proved that the sevoflurane had no harmful effect and can be considered as a safe inhalational drug.

Estrogenic Effect of Orthopedic DDT on the Female Genital Organs of Mice
Insecticide DDT (an organochlorine compound) has been used excessively and widely all over the world. It was shown that orthopedic DDT (o-p'-DDT) a major constituent of technical grade preparation of the pesticide- DDT exhibited estrogenic activity in several animals species (Welch et al., 1969 and Bitman et al., 1968).
The aim of this work is to study the estrogenic effects of o-p'-DDT on the female reproductive organs (ovary, uterus and vagina) of mice in its neonatal period.
In this study fifty of newly-born female mice were used and divided into five groups; three groups of them were received ten intraperitoneal injections of o-p'- DDT in doses of 0.25, 0.5 and 1mg/injection. The study included two control groups, the first one was injected with 10 ugm estrogen for 10 injections and considered as positive control, while the second group injected with sesame oil only. The animals were scarified 2 days after the last injection. Paraffin and frozen sections were prepared for both histological and histochemical studies. Different staining techniques were used including Hx., E., modified gomori stain for alkaline phosphatase enzyme, methyl green pyronin for RNA and PAS stain for glycogen content.
The results showed a distinct increase in number and size of ovarian growing follicles in those animals treated with o-p'-DDT, also, increased activity of the alkaline phosphatase enzyme, as well as increased content of RNA and glycogen was noticed. The effect of o-p'-DDT on the uterine structure were in the form of hypertrophy of the endometrial epithelium, also increase in number of uterine glands. Marked increase in the activity of alkaline phosphatase enzyme and also in RNA content as well as glycogen deposition.
It was noticed also that high dose of o-p'-DDT leads to accelerated development of the vaginal epithelium with evidence of keratinization. The histochemical changes in the vagina were similar to those obtained in the uterus.
It can be finally concluded that the obtained results after use of o-p'-DDT were similar to those obtained by estrogen, and this may interfere with implantation of ova and pregnancy.

The Protective Role Of Royal Jelly Against Sodium Nitrate And Sun-Set Yellow Toxcity In Albino Rats
In last few years, all over the world, food preservatives and favorable food colour are used in wide scale. However, their use in food still controversial.
It causes and will cause severe tension to the consumers as the sensitivity of people to general health increases.
This work was carried out to study the possible toxic effect of the interaction of one of food preservatives (sod. nitrite ) and one of the most favorable food colour (sun- set yellow) on rates. To study the effect of this interaction, a mixture of 1/10 of the limited dose of Na No3 and sun-set yellow was daily administered to rats. Other group was supplemented with royal jelly in combination with the mixture to evaluate its possible protective role during the course of experiment. Treatments were continued to 30 days, then half of the animals were sacrificed, the other half was left for 15 days after the last dose without any additional treatment (as a recovery period). The result can be summarized as follows:
Administration of sod. nitrite and sun-set yellow produced a significant decrease in percentage of body weigh, W.B.Cs, R.B.Cs, Hb, Hct, inorganic phosphorus, serum protein and serum albumin of rats.
A marked increase in respiration rate, serum glucose, T3, T4, calcium, -GT, LDH, CPK, alk. ph., serum cholesterol and (brain, liver and heart cholesterol) was recorded during treatment with the mixture.
Insignificant change in organ / b.wt., heart beat, rectal temperature, serum and tissue AST and ALT, serum acid phosphates, tissue proteins, serum and tissue total lipids muscle and kidney cholesterol and serum triglycerides was determined.
Administration of royal jelly and to some extent a recovery period ameliorated many hazards produced by using food additives. So, this study threw light on the bad behavior and its hazards of using food additives and food colour in the same time by our kids. It is also clear that royal jelly as a natural product nearly ameliorate these damage. So, it’s advisable to administered royal jelly to children and prevent if possible the using of additive and synthetic colour in their food.

Evaluation of Different Techniques in Diagnosing Chlamydial Endocervical Infection Among Egyptian Females
Objective: To detect the prevalence of Chlamydia. Trachomatis infection symptomatic and asymptomatic in Egyptian females and to evaluate the diagnostic utility of polymerase chain reaction (PCR), direct immunofluorescence technique (DIF), and enzyme-linked immunosorbent assay (ELISA) for detection of C Trachomatis DNA, antigen and antibody respectively.
Study design: The study included 70 females who have been classified into :20 patients with tubal infertility, 15 patients with ectopic pregnancy, 20 patients with premature rupture of membrane (PROM) and 15 apparently healthy women (asymptomatic group). Endocervical specimens, vaginal swab and 3 ml blood samples
have been collected from all subjects and stored at –20ْC till being processed.
PCR,DIF and ELISA techniques have been done to detect C. Trachomatis DNA, antigen and antibody respectively.
Results: C. Trachomatis DNA was detected by PCR in the endocervix of 17 out of 55 infected cases (30.9 % ). however DIF technique was positive for 21.6% of patient groups and 13.3% of asymptomatic group. The tubal infertility group showed the highest percentage of active C. Trachomatis infection (45%) (P<0.05) PCR showed better sensitivity than DIF for detection of C. Trachomatis infection (96.2% versus 70% respectively), however both techniques had 100% specificity. Tubal infertility group showed highest sero prevalence (45%), followed by ectopic pregnancy group (35%) (P= 0.001 and P<0.05 respectively).
Conclusions: PCR procedure is suitable for confirmation of ELISA results in high-volume laboratories. Cost, experience of the laboratory personnel and the patient well-being must be taken into account to select the test for the detection of C.Trachomatis infections.

Histological and Quantitative Study of the Effect of Eruca Sativa Seed Oil on The Testis of Albino Rat
Eruca Sativa (E.S) or Gargir seed oil is widely used in folk medicine. This study was conducted to investigate its possible effect on male rat fertility. Histological changes of the testis, level of testosterone hormone and sperm count were determined.
The results revealed that administration of low dose of E.S. seed oil caused dilatation of the seminiferous tubules, proliferation of spermatogenic cells and increase of its mitotic activity. Increased number of sperms and epididymis weight, elevated level of testosterone hormone and hyperplasia of interstitial Leydig cells have also been noticed. DNA analysis revealed an increase of the percentage of haploid and decrease of diploid and tetraploid cells. Administration of E.S. seed oil at higher dose showed. decreased diameter of the seminiferous tubules, reduced spermatogenic activity and number of sperms . Also testosterone hormone level decreased and the interstitial cells appeared few. DNA analysis showed a reduction of the percentage of the haploid and increase of the percentage of diploid and tetraploid cells.

Histochemical studies on the role of pantothenic acid on radiation damage of the kidney
The present study was designed to evaluate effect of pantothenic acid to gamma irradiated rats. Female albino rats (120-150gm) were subjected to (5 Gy) whole body 137Cs gamma irradiation. Fresh kidney specimens were obtained after 1 and 4 weeks of treatment. Frozen sections were prepared for histochemical study for localization of both acid, alkaline phosphatases and succinic dehydrogenase enzymes. The enzymatic activity was quantitatively evaluated and statistically analyzed. The obtained results showed significant decrease in both alkaline phosphatase and succinic dehydrogenase enzymes activity while the acid phosphatase enzyme activity was significantly increased in comparison to the control group after one week, while after four weeks the activity of both acid and alkaline phosphatase were significantly increased, while the enzymatic activity of succinic dehydrogenase decrease. Pantothenic acid treatment (22 mg/kg body weight / day for 6 days) after half hour of radiation showed marked improvement of the radiation induced changes in the activity of measured enzymes. Finally it could be concluded that pantothenic acid could be of value in improving the radiation injury on the kidney.
