Abstract
In this study, we examined the number and motility of sperms, and also observed the changes in testes weight, and histological changes of several organs after 5 days of a continuous administration of dioxin (2,3,7,8-tetrachlorodibenzo-p-dioxin) of per oral administration of a herb drug extracts, which were administerated altermate days, to elucidate the effects of the a herb drug extracts on reproductive toxicity of dioxin. 1. The sperm numbers of dioxin-administered groups were 90.7$\pm$3.6~l18.5$\pm$3.6$\times$10/suup 6/$m\ell$ and 67.3$\pm$4.1~88.2$\pm$3.3$\times$10$^{6}$ $m\ell$ for 10~20 $\mu\textrm{g}$/kg and 30~40 $\mu\textrm{g}$/kg dosages of dioxin-administerated groups, respectively. Each dioxin-administered group showed prominently lower value than that of control group's which was 119.3$\pm$3.4~120.2$\pm$4.7 $\times$ 10$^{6.}$$m\ell$. 2. The sperm motility of each dioxin-administered group's also showed lower value than that of control group's which was 93.6$\pm$3.8~94.9$\pm$3.4%. The sperm motility of each dioxin-administerated group were 77.0$\pm$4.7~89.5$\pm$3.6% and 66.5$\pm$3.3 ~79.9$\pm$3.8% for 10~20 $\mu\textrm{g}$/kg and 30~40 $\mu\textrm{g}$/kg dosages of dioxin-administerated groups, respectively. 3. The sperm numbers of each group, which was administered a herb drug extracts, were 77.4$\pm$3.2~90.9$\pm$3.4$\times$10$^{6}$ $m\ell$, 78.0$\pm$3.3~105.0$\pm$4.2$\times$10$^{6}$ $m\ell$, 76.2$\pm$2.8~84.4$\pm$3.5$\times$10$^{6}$ $m\ell$ and 75.4$\pm$3.3~80.2$\pm$3.3$\times$10$^{6}$ $m\ell$ for extracts of green leaf, red ginseng, Kugija and Oume-administered groups respectively. And the sperm motility of each group were 63.4$\pm$3.8~77.0$\pm$4.0%, 65.5$\pm$4.1~87.4$\pm$3.8%, 64.3$\pm$4.2~69.8$\pm$4.2%, 66.3$\pm$3.9~66.0$\pm$4.0% for extracts of green leaf, red ginseng, Kugija and Oume extracts-administered groups, respectively. 4. The number and motility of sperm of control group were 119.3$\pm$3.4~120.2$\pm$4.7$\times$10$^{6}$ $m\ell$ and 93.0$\pm$3.5~96.1$\pm$3.5%, respectively. Red ginseng extracts- administered group seemed to be recovered than my other groups, and the green leaf extracts-administered group was shown to be the next. The Kugija and Oume extracts-administered groups didn't show to be recovered much. 5. Most a herb drug extracts-administered group except the red ginseng-administered group displayed prominently lower values of testes weights than that of control group's which was 0.15$\pm$0.01~0.16$\pm$0.01g. The red ginseng extracts-administered group seemed to be recovered conspicuously. 6. After 5 days of a continuous administration of 30 $\mu\textrm{g}$/kg dosage of dioxin followed by 3 weeks of per oral administration of green leaf, red ginseng, Kugija, or Oume extracts, histological findings showed that the liver, spleen, and testis of most a herb drug extracts-administered groups were damaged severely. By the way, the testes of red ginseng extracts-administered group seemed to recover compared to the other group's.ompared to the other group's.
본 연구는 생약제재가 dioxin의 연속투여시 생식독성 완화에 미치는 영향을 구명하고저 30 $\mu\textrm{g}$/kg의 dioxin을 5일간 연속투여 후 생약제재를 3주간격일로 경구투여 했을 때 정자수, 정자활력, 정소중량 및 정소조직에 미치는 영향을 조사하였다. 1. Dioxin 10~20 $\mu\textrm{g}$/kg을 5일간 연속투여한 군의 정자수는 90.7$\pm$3.6~l18.5$\pm$3.6$\times$$10^{6}$$m\ell$, 30~40 $\mu\textrm{g}$/kg투여군의 정자수는 67.3$\pm$4.1~88.2$\pm$3.3$\times$$10^{6}$$m\ell$로서 대조군의 119.3$\pm$3.4~120.2$\pm$4.7$\times$$10^{6}$$m\ell$에 비해 현저히 감소된 정자수를 나타냈다(p<0.05). 2. dioxin 10~20 $\mu\textrm{g}$/kg 투여군의 정자활력은 77.0$\pm$4.7~89.5$\pm$3.6%, 30~40$\mu\textrm{g}$/kg 투여군은 66.5$\pm$3.3~79.9$\pm$3.8%로서 대조군의 93.6$\pm$3.8~94.9$\pm$3.4%에 비해 현저히 감소된 정자활력을 나타냈다(p<0.05). 3. Dioxin 30 $\mu\textrm{g}$/kg을 5일간 연속투여 후 녹차, 홍삼, 구기자, 오메 추출물을 격일로 3주간 투여했을 때 정자수는 각각 77.4$\pm$3.2~90.9$\pm$3.4$\times$$10^{6}$$m\ell$, 78.0$\pm$3.3~105.0$\pm$4.2$\times$$10^{6}$$m\ell$, 76.2$\pm$2.8 ~84.4$\pm$3.5$\times$$10^{6}$$m\ell$, 75.4$\pm$3.3~80.2$\pm$3.3$\times$$10^{6}$$m\ell$이었다. 4. Dioxin 30 $\mu\textrm{g}$/kg을 5일간 연속투여 후 녹차, 홍삼, 구기자, 오메 추출물을 격일로 3주간 투여했을 때 정자활력은 대조군의 119.3$\pm$3.4~120.2$\pm$4.7$\times$$10^{6}$$m\ell$와 93.0$\pm$3.5~96.1$\pm$3.5%에 비해 홍삼추출물 투여군에서는 회복이 현저하였고(p<0.05), 녹차는 다음이었으며, 구기자, 오메는 회복이 미미하였다. 5. Dioxin 30 $\mu\textrm{g}$/kg을 5일간 연속투여 후 녹차, 홍삼, 구기자, 오메 추출물을 각각 격일로 3주간 투석했을 때 정소중량은 대조군의 0.15$\pm$0.01~0.16$\pm$0.01g에 비해 낮은 치를 나타냈으며 홍삼추출물 투여군에서는 회복효과가 현저하였다. 6. Dioxin 30 $\mu\textrm{g}$/kg을 5일간 연속투여 후 녹차, 홍삼, 구기자, 오메를 각각 3주간 격일로 경구 투여했을 때 간, 비장 및 정소조직은 대조군에 비해 심한 손상이 관찰되었으며, 정소는 홍삼 투여군에서 많은 회복이 관찰되었다.
