Adult male albino rats were treated with 0.5 mg and 0.75 mg morphine/100 g body weight intraperitoneally for 30 days. All the animals were autopsied on $31^{st}$ day. Epididymis and vas deferens were dissected out, weighed and processed for histological and biochemical studies. Morphine has caused a reduction in the weight of epididymis and vas deferens in both the doses of drug treated groups. The total cholesterol content is increased while protein, DNA and RNA contents and epididymal sperm counts are decreased. The acid phosphatase content is decreased 10.12 $\pm$ 0.11 in caput, 9.26 $\pm$ 0.30 in cauda of epididymis and in vas deferens 8.14 $\pm$ 0.15 in 0.5 mg treated groups and in 0.75 mg treated rats shows 9.52 $\pm$ 0.27 in caput, 9.14 $\pm$ 0.18 in cauda of epididymis and in vas deferens 7.84 $\pm$ 0.11is decreased, whereas alkaline phosphatase is increased. The surface epithelial cell height of these ducts is reduced and secretory activity is inhibited with the disruption of epithelial cell projections. The gravimetric and histometric changes of epididymis and vas deferens may be due to non-availability of androgens in morphine treated rats.

Molecular karyotyping was applied to Pneumocystis carinii (Pc) from two strains of experimental rats, Sprague Dawley(SD) and Fisher(F), in Korea. Field inversion gel electrophoresis and contour clamped homogeneous electric field electrophoresis resolved 15 chromosomal bands from the Pc. The size of the bands was estimated 270kb to 684kb from SD rats, and 273kb to 713 kb from F rats. The bands of 283 kb from SD rats and of 273 kb from F rats stained more brightly suggesting duplicated bands. Total number of chromosomes was at least 16, and total genomic size was estimated 7×106 bp. All of the bands from F rats hybridized to the probe of repeated DNA sequences of Pc and the band of 448 kb size was proved to contain rDNA sequences, but Pc. chromosome bands from SD rats showed no reactions to the probes. The 2 different karyotypes of p. carinii from 2 strains of rats were maintained consistently for 2 years.

Purpose: Due to the increasing prevalence of obesity worldwide, non-alcoholic fatty liver disease (NAFLD) has reached epidemic dimensions over time. NAFLD is the most common cause of childhood chronic liver disease. There is a relationship between NAFLD and oxidative stress. This study aims to investigate the changes in thiol/disulfide homeostasis parameters to determine the oxidant/antioxidant balance in obese rats with diet-induced NAFLD and healthy rats. Methods: Twelve Wistar albino rats were used in this study. Experimentally produced NAFLD obese rats (n=6) and healthy rats were compared. Experimental NAFLD model was created with a special fatty liver diet (Altromin^® C1063, Fatty Liver Diet, Exclusivet, Lage, Germany). The biochemical and histopathological features of the groups, as well as serum thiol/disulfide homeostasis parameters, were analyzed and compared. Results: In the experimentally induced NAFLD rat model, they gained more weight than the control group. Steatosis (at least grade 2) occurred in all rats fed with special fatty liver diet for 12 weeks. Histopathologically, no high-grade inflammation was observed in rats with experimental NAFLD after feeding a diet for 12 weeks. Results revealed that aspartate transaminase and alanine transaminase levels were high, albumin levels were low, oxidant stress parameters increased, and antioxidant thiol groups decreased. Conclusion: Experimental NAFLD is characterized by increased oxidant stress accompanying fatty tissue in the liver. Analysis of thiol/disulfide homeostasis parameters in NAFLD can be used in further studies to develop effective treatment options.

The acute oral, intraperitoneal and subacute toxicity of monocrotophos, an insecticide, was studied in albino rats. The acute oral $LD_{50}$ values for female and male rats were 5.0mg/kg and 8.7mg/kg, respectively. Conversely the intraperitoneal $LD_{50}$ values for female and male rats were 4.9mg/kg and 6.0mg/kg, respectively. Plasma cholinesterase (ChE) activity in rats treated with a single dose was the most depressed 4 hours after administration, but returned to normal within 72 hours of administration. Significant depression of body weight gain and food consumption was observed in rats receiving the 3.5mg/kg/day dose level for 28 days as compared with the controls. Additionally plasma ChE activity depression was also observed.

Dichrostachys cinerea (Linn.) is commonly known as Vadatalla and used as phytotherapeutic agent. Tender shoots of the plant bruised and applied to the eyes in case of ophthalmia. The root is astringent and used in rheumatism, urinary calculi and renal troubles. The effect of the Ethanolic and aqueous extract of the root of D. cinerea were studied for its anti-urolithiatic and diuretic activity at 200 mg/kg dose level in male Wistar albino rats. Ethylene glycol feeding resulted in hyperoxaluria as well as increased renal excretion of calcium and phosphate. Supplementation with aqueous and ethanolic extract of the plant significantly reduced the elevated urinary oxalate, showing a regulatory action on endogenous oxalate synthesis. Compared to ethanolic extract, aqueous extract exhibited significant anti-urolithiatic activity. Both the extracts showed significant diuretic activity. The results of our present study supports folklore claim of D. cinerea.

Synthetic coumarin and furocoumarin derivatives were evaluated for anticoagulant activity and the effect on liver and kidney function. It was found that all of the compounds under investigation proved to be neither toxic nor lethal up to 500 mg/100 g body weight as a single dose for 24 hrs. All tested compounds showed a significant increase in prothrombin time (PT) in the acute model but failed to show a significant action in the chronic model. Furthermore, all tested compounds revealed a significant increase in activated partial thromboplastin time (APTT) as compared to control value in both acute and chronic model. Also, all tested compounds did not cause any significant changes on liver and kidney functions in rats.

This study was divised to observe the effects of ginseng on the body components of Sprague-Dowley Albino male rats by alternating the diet. Just weaned rats (130 heads, weighing(83 ${\pm}$ 4g) were fed with each stock diets supplemented with 0.5, 1.0 or 3.0% ginseng powder for 4 weeks or 8 weeks, and after that fed with stock diet only for 8 or 4 weeks. Compared with the each corresponding group which was fed with ginseng control diet, the protein, total lipid, total cholesterol and free cholesterol contains in serum, liver and aorta of them were determined. The results obtained was summarized as follows ; Protein and total lipid contents of the rat were decreased, caused by the alternating diets, but total cholesterol and free cholesterol contents were increased in the serum, protein and free cholesterol contents increased, conversely total lipid contents decreased in the liver, and in aorta total lipid and total cholesterol contents decreased, In the view of the above results, it can be seen that the alternating diet (stock diet after feeding with ginseng diet) has an influence on the body components of rat.

1) The general composition, vitamin, amino acid, digestibility and nutrition efficiency of the seeds of Pinus Koraiensis Sieb. et Zucc. were examined. (2) Pine tree seed contains approximately 17% or more protein nearly pure one. The amino acid composition of the protein was analyzed. When compared with the values of soybean and peanut reported in the literature, it contains slightly mare histidine and glycine etc., showing that the seeds are of high nutritional value. (3) The protein digestibility was 87% and the total content of digestible protein was approximately 14.9%, T.D.N. was 159.4%, proving itself excellent. (4) As to vitamins, it was found out that the seeds contain 275 r of $B_1$ and 99 r. As to minerals, Ca (301.2 mg) P (361 mg) and K (272 mg) were found to be contained in the seeds (5) The basic diet was considered nearly perfect from the view-point of nutrition, and to this were added 30%, 5% and 10% of the test sample respectively and were fed to albino rats. Among the three treatment, the 3% sample adding proved to be the mast effective one, showing the most efficient growth. Thus it can be presumed that the pine tree seeds certainly contain U.G.F. (6) The anatomical examination of the intestines of albino rats showed that the feeding of pine tree seeds bad favorable effect on the development of heart, kidney and pancreas.
