This study was carried out to investigate preventive effects of extracts of cricket, Gryllus bimaculatus, against the 2,3,7,8-tetrachlorodibenzo-p-dioxin(TCDD)-induced toxicity in 7-week-old Sprague-Dawley male rats. Thirty five male rats were divided into 5 groups: one normal control group treated with vehicle and saline (G1); one TCDD-treated group by single intraperitoneal injection (G2); three preventive groups (G3, G4, and G5). The last three groups, G3, G4, and G5, were fed on cricket extracts (50, 100, and 200 mg/kg, respectively) for 2 weeks before TCDD treatment. Various harmful effects were shown by TCDD treatment. The body weights of rats were lost by TCDD. In addition, severe hypertrophy and color change, and the weights gaining were found in the livers of TCDD-treated rats. It was observed that the cytoplasmic vacuolizations and inflammatory cell infiltration around portal triad in the liver. TCDD also elevated the serum activity levels of alanine transaminase(ALT) and aspartate transaminase(AST). However, those losses were compensated by cricket extracts treatment at the level of 200 mg/kg. These findings indicate that cricket extracts may have protective effects against TCDD-induced toxicities in rats.

The cricket has been used in East Asia as crude drugs for treating fever and hypertension, and is presently reared as a pharmaceutical insect in China and a food for animals. For the purpose of evaluating protective extracts against alcohol-induced toxicity, the extracts of the cricket (Gryllus bimaculatus) were examined in animal models acutely administered alcohol by the cricket in ICR-mice. Water and methanol extracts from the cricket, were found to cause a significant decrease (37%) in the blood ethanol concentration as well as enhancement of liver mitochondrial alcohol dehydogenase (ADH) and acetaldehyde dehydogenase (ALDH) activitieson on a single intraperitoneal administration in mice. Futhermore methanol extract was demonstrated to exhibit more potent enhancing activity on ethanol metabolism than water extract. These results suggest that water/alcohol extract of G. bimaculatus may be used as a food for reducing the toxicity of alcohol.

귀뚜라미의 곤충산업의 발달로 대량체계화 사육된 귀뚜라미의 새로운 용도 개발의 일환으로 귀뚜라미의 간보호 효과를 조사하였다. 사염화탄소로 6주령의 ICR 응성 생쥐에 급성간염을 유발시킨 후 귀뚜라미 물 추출물(20 mg/kg) 및 메탄올 추출물(20 mg/kg)을 각각 투여하여 GOT, GPT, LDH 간혈청 효소 활성을 조사한 결과 귀뚜라미 메탄올 추출물은 대조구에 비해 GOT, GPT, LDH치가 74, 50, 101% 감소하였다. 지질과산화 억제정도는 귀뚜라미 물추출물 및 메탄올추출물이 정상군 대비 40%이상의 억제 효과를 나타내었다. 또한 강제수영법에 의한 귀뚜라미 추출물의 항피로 효과를 측정시 대조군에 비해 메탄올 200 mg/kg에서 현저한 수영시간 증가를 보여 양성대조군인 토코페롤 100 mg/kg 수준의 유의성 있는 항피로 효과를 나타낸 것을 알 수 있었다. 이상의 결과로 보아 귀뚜라미의 수용성 및 알콜추출물은 간보호 효과를 가지는 건강보조식품으로서 개발 가능성을 가짐을 알 수 있다.
