Cassia obtusifolia L. is commonly used as medicinal foods to treat gastrointestinal disease in many countries. This study evaluated the anti-constipation effects of ethanolic extract of Cassia obtusifolia L. in rats with loperamide-induced constipation. Diffferent concentrations of ethanolic extract of Cassia obtusifolia L. (0, 10, 250, and 500 mg/kg) was administered to rat orally once daily for 3 weeks following loperamide treatment. Six-week-old Sprague-Dawley rats (N=25) were randomly divided into five groups: normal control and experimental groups and injected loperamide intraperitoneally to induce constipation in the latter four experimental groups. Following the induction of loperamide-induced constipation, a marked decrease was observed in the fecal weight and water content discharged for over 1 week and intestinal transit time while an increase was observed in the number of fecal pellets remaining in the colonic lumen as compared with the normal control group. These conditions were significantly alleviated following the administration of the two doses (250 and 500 mg/kg) of ethanolic extract of Cassia obtusifolia L. when compared to the loperamide-treated (constipation control) group. More specifically, the number of fecal pellets in the colon was 3, 5, 4, 2.8, and 1.2 in the five groups, respectively and the corresponding GIT ratio was 70.77, 56.59, 58.67, 66.81, and 72.10%, respectively. The fecal water content, transit distance, and GIT ratio in the high-dose treatment group were significantly higher than that in the medium-dose treatment group, but a significant decrease in the number of fecal pellets in the colon. In conclusion, the Cassia obtusifolia L. extract is suggested to have beneficial effects as a therapeutic and preventive strategy to alleviate constipation and to relieve the symptoms of constipation such as pain, flatulence, distention, bloating, and unpleasant taste.

As the population ages, the number of households raising companion animals is increasing. Companion animal industry has recently been diversified through a combination of various industries such as beauty, rest, and insurance, and the share of this industry in the economy is gradually increasing. Dandruid keratoses, ticks, and various pathogenic bacteria are parasitized on the skin and hair of a dog to damage the hair and cause skin diseases. The purpose of this study was to investigate the effects of natural ingredients on the oil and moisture content of dog skin when using natural shampoos and using these shampoos. In this study, we measured the water content of four poodles of 1 year and 4 years old. The natural shampoo used in 4 rats was prepared and used directly. The results of this study showed that the water content in the forelimb of the experimental dog was almost unchanged when using the ordinary shampoo, but it increased with the use of the natural shampoo. Especially, when using natural shampoo for 3 weeks, it was confirmed that the water content of ordinary shampoo increased about 55.71% over 3 weeks. On the other hand, when using a general shampoo, the water content of the neck of the experimental dog was almost unchanged, and even when using the natural shampoo, the moisture content was almost unchanged. These results suggest that natural shampoos will have a better effect on maintaining the moisture content of companion animals compared to ordinary shampoos.

재래유자, 개량종 I(유자+탱자), 개량종 II(유자+유자) 세가 지 유자의 종류별, 부위별 이화학적인 특성과 유기산, 지방산 및 향기성분을 분석하였고, 총 페놀 화합물을 분석하는 실험 을 수행하였다. 중량은 재래종이, 껍질(혹은 껍질+씨)의 비율 은 개량종이 높았다. 단백질은 재래종보다 개량종Ⅰ의 껍질 에서 다소 높게 나타났고, 회분도 개량종의 껍질에서 다소 높 았다. Vit. C는 과즙의 경우 재래종에서 29.6 ㎎%로 껍질에서 는 개량종 I이 57.7 ㎎%로 다소 높았다. 유리당은 과당이 주 였는데, 개량종 I에서 가장 높은 함량을, 유기산은 구연산이 대부분을 차지하였는데, 개량종 II에서 가장 유기산 함량이 높았다. 유자의 지방산 조성은 리놀레인산이 가장 많았고, 과 피와 과즙에서 품종별 특징을 보이고 있었다. 향기성분은 dl-Limonene이 향기성분의 64~70%를 차지하는 물질로, gammaterpinene과 함께 개량종 II에서 유의하게 높았다. 유자에 함 유된 총 페놀 함량은 품종별로는 유의한 차이를 보이지 않았 으나, 과즙에 비해 과피에 2.5배 정도 많은 양이 들어 있었다.
