General pharmacological studies of LB20304a (a mesylate salt form of a new quinolone antibiotic LB20304 following oral administration of 300 mg/kg and 1000 mg/kg, almost maximum tolerance dose in mice and rat, respectively, were performed in terms of effects on general behaviour, central nervous system, gastrointestinal system, and blood coagulation system in mice and rats. With regards to general behaviour of mice, at oral dose of 300 mg/kg, LB20304a reduced muscle tone and locomotor activity. In terms of CNS, at oral treatment of 300 mg/kg, LB20304a showed some analgesic effects in mice, and oral dose of 1000 mg/kg caused drop in normal body temperature of rat, while it enhanced the pentylenetetrazole-induced clonic convulsion to tonic convulsion and/or death in mice at the doses of unto 300 mg/kg. In addition, LB20304a increased hexobarbital-induced sleeping time two and three times in mice at oral doses of 20 mg/kg and 300 mg/kg, respectively. Rota-rod and traction test in mice were not influenced by the dose of 300 mg/kg and 200 mg/kg, respectively. LB20304a reduced gastric secretion of rat at dose of 1000 mg/kg, and increased intestinal motility of mice at dose of 300 mg/kg. In rats, blood coagulation index, such as PT (prothrombin time) and aPTT (activated partial thromboplastin time) were not affected by the treatment of upto 1000 mg/kg of LB 20304a.

We investigated the effect of Arogh, a polyherbal formulation (PHF) on animal models of anxiety based on exploratory behavior. The anxiolytic activity of polyherbal formulation (30, 100, 300 and 500 mg/kg) was studied using various behavioural paradigms such as elevated plus maze (EPM), light/dark apparatus (LDA), open field apparatus (OFA), hole board apparatus (HBA). Diazepam (1 mg/kg) was used as a standard anxiolytic drug. The effect of PHF (100 and 300 mg/kg) on serotonin, dopamine and noradrenaline mediated behaviour was studied by lithium induced head twitches in rats, haloperidol induced catalepsy in mice and clonidine induced hypothermia in rats respectively. In EPM, PHF (100, 300 and 500 mg/kg) significantly (P < 0.05) increased the time spent in open arms and the number of entries in open arms. In LDA, PHF (100, 300 and 500 mg/kg) significantly (P < 0.05) increased the time spent in lit zone. In OFA, PHF (100, 300 and 500 mg/kg) significantly (P < 0.05) increased the number of assisted rearing and the number of squares traversed. In HBA, PHF (100, 300 and 500 mg/kg) significantly (P < 0.05) increased the number of head poking. In lithium induced head twitches, PHF (100 and 300 mg/kg) significantly (P < 0.05) decreased the number of head twitches. In haloperidol induced catalepsy, PHF (300 mg/kg) decreased the duration of catalepsy significantly (P < 0.05) at 60 min. In clonidine-induced hypothermia, PHF (300 mg/kg) did not modify the effect. Drugs must be carefully assessed on EPM test and therefore in the present study EPM is supported by other tests. Present study indicates that Arogh, a polyherbal formulation possess anxiolytic activity. It diminished serotonergic transmission and decreased the duration of catalepsy indicating potentiation of dopaminergic transmission. Thus, Arogh a polyherbal formulation contains bioactive principles which possess anxiolytic activity and modified 5-HT and DA mediated behaviour.

Objectives: The present study was conducted in order to investigate the reproductive toxicity in rats exposed to 1,4-dichlorobutane. Methods: The test chemical was administered orally at 0, 8.3, 50 and 300 mg/kg/day. Males were administered daily for 10 weeks prior to the mating period. Females were administered from between two weeks before mating to the 21stday of lactation. Results: In both sexes, a decrease in body weight and an increase in the weights of the liver and kidneys were observed. In males, discoloration of the liver, hepatocyte hypertrophy and mineralization in the kidneys were observed. In females, animal deaths, dystocia and pup deaths due to maternal dysfunction were observed. In F1 animals of both sexes, a decrease in body weight was observed at 300 mg/kg/day. An increase in the weights of the liver in both sexes, mineralization in the kidneys of males, animal deaths, hepatocyte hypertrophy and pup deaths due to maternal dysfunction were observed at 50 mg/kg/day. Mineralization in the kidneys of males was observed at 8.3 mg/kg/day. Therefore, the no-observed-adverse-effect levels (NOAELs) of 1,4- dichlorobutane were considered to be under 8.3 mg/kg/day for males, 8.3 mg/kg/day for females, more than 300 mg/kg/day for fertility in both sexes, 8.3 mg/kg/day for maternal functions and 50 mg/kg/day for F1 offspring. The absolute toxic dose was believed to be 8.3 mg/kg/day for males, 50 mg/kg/day for females, 50 mg/kg/day for maternal functions and 300 mg/kg/day for F1 offspring. However NOAEL for fertility could not be determined since there were no treatment-related changes. Conclusions: Under the present experimental conditions, 1,4-dichlorobutane is a Category 1B Reproductive Toxicant (presumed human reproductive or developmental toxicant).

본 연구는 울금의 산업적 실용화를 극대화시키기 위해 Aspergillus oryzae를 이용하여 산업용 규격에서 생산된 발효울금의 일반성분 및 미량성분 분석과 발효울금을 이용하여 동물모델에서 14일간 예비 투여하고 GalN으로 급성 간독성을 유발한 후 혈액 중 간기능 지표물질의 변화 및 간조직의 조직학적 관찰을 통해 GalN로 유발된 급성 간독성에 발효울금의 간기능 보호효과를 평가하고자 하였다. 발효울금의 일반성분은 수분 0.15%, 조지방 4.68%, 조단백 4.35%, 조섬유 6.92%, 조회분은 6.83%로 분석되었다. 발효울금의 미량성분은 P, Mg, Ca 순으로 분석되었다. 간기능 지표효소인 AST와 ALT의 활성은 발효울금 300 mg/kg/day과 silymarin 150 mg/kg/day를 투여한 군에서 GalN만을 투여한 군과 비교하여 통계적으로 유의한 결과를 나타내어 발효울금 300 mg/kg/day의 예비 투여는 GalN에 대한 급성 간독성에 대해 보호효과를 갖으며, 양성 대조군인 silymarin 150 mg/kg/day 투여와 비교하여 유사한 간독성 보호 활성을 갖는 것으로 나타났다. ALP의 경우 발효울금을 100 mg/kg/day로 투여한 군에서만 GalN만을 투여한 군과 통계적으로 유의한 감소를 나타났고 300 mg/kg/day 발효울금을 투여한 군과 silymarin 투여군은 통계적 유의차가 나타나지 않았다. 중성지방의 경우 발효울금 300 mg/kg/day 투여군만 GalN만을 투여한 군과 비교하여 통계적 유의차가 나타났으나 silymarin 투여군에서는 동일한 효과가 나타나지 않았다. GalN으로 유도된 급성 간독성의 조직병리학적 결과 GalN만을 투여한 군에서 세포괴사 및 침윤된 염증세포, 카운실만소체의 괴사가 심하게 나타났으며 300 mg/kg/day 발효울금 투여군과 150 mg/kg/day silymarin 투여군에서 간조직의 괴사 및 염증의 개선효과를 관찰할 수 있었다. 혈청 분석 및 조직병리학적 결과를 종합한 결과 GalN 유발 간독성에 대한 개선효과는 300 mg/kg/day 발효울금 투여군과 150 mg/kg/day silymarin 투여군에서 나타나는 것으로 판단할 수 있었다. 이러한 결과로부터 본 연구에서 사용한 Aspergillus oryzae로 발효하여 산업적 규격에서 생산된 발효울금은 간기능 저하 개선 기능을 갖는 새로운 기능성 소재로서 간질환과 관련된 다양한 기능성식품 개발에 이용될 수 있을 것으로 생각된다.
