  • In present study evaluate the analgesic and anti-inflammatory activity of the compound obtained from the petroleum ether (40 - 60$^{\circ}C$) extract of the fruits from Dregea volubilis in Swiss albino mice and in Wister albino rats respectively. Dried and crushed fruits of Dregea volubilis were extracted by petroleum ether (40 - 60$^{\circ}C$), the proper solvent system was developed by TLC and subjected to column chromatography for obtaining the pure compound/s. IR, MASS, NMR (PMR, C13 NMR and DEPT) spectroscopic analysis were done to elucidate the structure of the compound/s. The petroleum ether (40 - 60$^{\circ}C$) extract of the fruits of Dregea volubilis led to isolation of a pentacyclic triterpenoid designated as taraxerone and characterized as D- friedoolean- 14- en, 3 one. Taraxerone had been screened for analgesic activity in Swiss albino mice and anti-inflammatory activity in Wister albino rats at the dose of 5 mg/kg body weight orally and exhibit significant analgesic and anti-inflammatory properties.

  • The purpose of this study was to determined the effect of low-frequency electrical stimulation on the denervated gastrocnemius muscles of the albino rats, Sprague-Dawley. Fifteen Sprague-Dawley adult male albino rats were divided into non-treated (normal) group, denervated (control) group, denervated and electrical stimulated (experiments). The gastrocnemius muscles of the right leg were submaximally stimulated with 30 Hz electrical stimulation. After 4-week period, the animals were sacrificed, and muscle were removed, fixed by immersion, and processed for light and electron microscopy. The numbers of Ag-NOR increased significantly (p<0.001), but significant reductions of girth(p<0.01), wet muscle weight (p<0.001), high glycogen content fiber (p<0.01), and mitochondrial number (p<0.05) were found in denervated control group. In comparison with control group, significant increase of right leg girth (p<0.05), wet muscle weight (p<0.001), high glycogen content fiber (p<0.05), numbers of Ag-NOR(p<0.001), number of mitochondria (p<0.01), mitochondrial volume found in electrical stimulated experimental group. The results suggest that the electrical stimulation of the muscle partially prevented the denervated atrophy in the rat gastrocnemius muscles.

  • An attempt has been made to assess whether the dose dependent effect of benzene extract of Ocimum sanctum leaves on the morphological changes in the cauda epididymal spermatozoa and sperm parameters in male albino rats. Scanning Electron Microscope observations illustrate the disturbance in plasma membrane as well as acrosomal membrane. Most of the sperms appear morphologically abnormal in the mid region of the tail; there is formation of balloon like cytoplasmic droplet. Sperm parametric study exhibits decrease in the total sperm count, sperm motility, forward velocity and increase in the percentage of abnormal sperms in dose dependent manner on treatment benzene extract of Ocimum sanctum leaves. The results suggest that the effects may have resulted from a general disturbance in the proteins and alteration in cauda epididymal milieu probably due to androgen deficiency consequent upon antiandrogenic property of Ocimum sanctum leaves.

  • The developmental features, growth and organogenesis of Macroorchis spinuiosus were observed in albino rats. Globular and thick walled metacercariae, possessed a stylet, Y-shaped excretory bladder and extracecal testes. Un albino rats, M. spinulosus showed habitat shifting. The majority of M. spinulosus reside in the jejunum for the first four days post Infection (p.i.) and migrate to the duodenum at the later stage of infection. M. spinulosus grew rapidly during the first four days and reached full maturity at 14 days p.i. and later reduced in size. The ovary was separated from the genital primodium at one day p.i. The seminal vesicle appeared on the third day and divided into two sacs on the fourth day p.i. and intrauterine eggs and sperm mass were produced on the fourth day. Organogenesis and enlargement of reproductive organs governed the growth of M. spinulosus. The similarity of related species of the genus Macroorchis to M. spinulosus was discussed In consideration to developmental features.

  • 몇가지 실험동물의 Firbricola seoulensis 실험감염에 대한 감수성을 알아보고 숙주로서의 적합도를 관찰하고자 중간숙주로 알려진 뱀으로부터 피예유충을 분리하여 50∼2,000개군으로 나누고 횐쥐, 마우스, 개, 고양이, 토끼 및 닭등 총 127마리에 각각 실험감염시킨 다음 3일부터 8주까지 각 숙주내에서의 충체회수률 및 충체성숙도를 관찰하고 비교분석 하였다. 그 결과는 다음과 같다. 1. 총 충체회수률은 횐쥐에서 가장 높아 40.0%이었으며, 그 다음이 마우스로 33.9%이었고, 고양이 20.9%, 개 11.4%, 토끼 0.05% 및 닭 O%의 순으로 나타났다. 충체회수율은 감염기계이 길어짐에 따라 차차 저하되는 경향을 보였으며 감염피낭유충수에 따라서도 다양하게 변화하는 것으로 나타났다. 2. 횐쥐에는 피예유충 1,000개를, 마우스에는 200개를 감염시켰을때 충체회수률이 가장 높았으며 이 정도의 파낭유충수가 이들 동물을 감염시키는데 적당한 감염량으로 생각되었다. 3. 각 실험동물에서 주 기생부위는 소장이었고 고 중에서도 특히 십이지장이었다. 4. 각 동물에서 회수한 충체의 성숙도(성숙충체수/관찰충체수)는 횐쥐와 마우스에서 모두 100%이었고 개에서는 22.7%이었으며 고양이에서는 0%로 전혀 성숙된 충체가 없었다. 이상의 결과를 종합해볼 때 6종의 실험동물중 충체회수율 및 총체성숙도가 높은 횐쥐와 마우스가 Fibricola seoulensis의 가장 좋은 호적숙주로 생각되었다.

  • In the present investigation twelve indigenous medicinal plants have been screened for their antiimplantation activity in albino rats. The plant material was subjected for soxhlation successively and separately from non-polar solvents to polar solvents i.e., petroleum ether benzene and ethanol. Out of these three extracts the petroleum ether extract of seeds of Citrus medica, aerial part of Oxalis corniculata and Tinospora cardifolia have showed maximum antiimplantation activity. Ethanol extract of leaves of Cardiospermum helicacabum, roots of Echinops echinatus, leaves of Melia azedarach, seeds of Momordica charantia and bark of Terminalia bellirica have shown maximum antiimplantation activity amongst the three extracts of each plant material screened. Though all the three extracts of seeds of Annona squamosa and leaves of Zizyphus jujube screened for antiimplantation activity, no extract has showed any loss in implantation. The details of the results obtained are discussed.

  • Liver and kidney are specific organs which play an active role in biotransformation and detoxification mechanisms. Ant adverse effect of chemicals or heavy metal can cause the delay or fade in these mechanisms. Present study was designed to find out the protective effect of Panax ginseng extract on renal functions altered by mercuric chloride (heavy metal) in albino rat. Fifty albino rats were divided into 10 groups. Five groups for acute study and five groups for sud-acute study viz. control group (Tween 20 and distilled water), mercuric chloride treated group (0.926 mg/kg body wt. for acute and 0.044 mg/kg body wt. for sub-acute group after calculated $LD_{50}$ (9.26 mg/kg body wt.) by probit analysis (Finney, 1971), Panax ginseng extract treated group (10 mg/kg body wt. for acute and sub-acute sets), mercuric chloride treated followed by Panax ginseng extract and Panax ginseng extract followed by mercuric chloride group. All doses were given orally by gavage tube. The result revealed that the serum urea and creatinine significantly increased in mercuric chloride treated group, while significantly decreased (p<0.01) in Panax ginseng extract group after acute and sub-acute treatment. The biochemical estimation is also confirmed by nephropathological aspect. However, the Panax ginseng extract treated followed by mercuric chloride group is more prominent than the mercuric chloride treated followed by Panax ginseng extract group. It can be concluded that Panax ginseng extract had a protective nature on renal functions against mercuric chloride toxicity in albino rats.

  • The effect of methionine supplementation to the isolated soyprotein(ISP) diet on the growth, body metabolism and composition of the Albino male rats was studied. Three levels(0.3,0.6 and 0.9%) of methionine were supplemented to the ISP diet with the constant levels of energy and protein of 3,600 kcal/kg and 20%, respectively. The body weight and weight gain of the growing rats were significantly increased by 0.3% methionine supplementation to the ISP diet compared to the ISP diet(P< 0.05).The effects of methionine supplementation to the ISP diet tended to be larger with increasing of the level of methionine supplementation, 0.6 and 0.9%, were statistically insignificant. Food and gross energy intake of growing rats fed the ISP diet or the ISP supplemented with methionine diet were lower than those fed the casein diet(P< 0.05). FER and PER of all the methionine supplemented diets were higher than those of the ISP or casein diet (P< 0.05) without significant differences among the supplementation levels of methionine to the diets. The weight gain of adult rats fed 0.9% methionine supplemented ISP diet were higher than those of the other treatments with significant difference. The effects of methionine supplementation to the ISP diet on the protein digestibility, BV, NPU, N-balance, N-retention, and body and liver compositions were not significant.
