N/A Genital organs and gonad development in kishi velvet shrimp (Metapenaeopsis dalei) were studied based on morphological and histological observations. The samples were collected monthly around the Ochongdo area on the western coast of Korea, from April 1997 to December 1998. Thelycum appear structurally complete after females reach a length of about 12.0 mm CL. Petasma rarely join after males reach a length of 10.6 mm CL and a fully developed petasma shows up to a length of 12.0 mm CL. The ovaries lie on the dorsal side of the female shrimps thorax. The ovary cavity is located below the heart and above the hepatopancreas. The anterior part of the ovary is round and fused, and the posterior part shows a pair of tubule-like structures. Testes are bilaterally symmetrical; the anterior part shows a convoluted tubule, and the posterior part consists of a pair of tubules. In histological observations, ripe eggs and spermatozoon show when mature females and males reach a length of about 12.0 mm CL.

Naesosan(NSS) has been used in Oriental Medicine as a drug that treated carbuncle and cellulitis. So, the purpose of this Study was to investigate effects of NSS on the cytotoxicity of cancer cell lines and lymphocytes in vitro, proliferation of Ll210 cells and lymphocytes in L1210 cells transplanted mice, improvement of blood count in Ll210 cells transplanted mice, tumor weight and body weight in sarcoma-180 cells transplanted mice, survival prolongation in sarcoma-180 cells transplanted mice. We used NSS extract with freeze-dried, 8wks-old male mice(balb/c and ICR mouse $18{\pm}2g$). Ll210 cell lines, and sarcoma-180 cell lines for this Study, The proliferation of cells was tested using a colorimetric tetrazoliun assay(MTT assay). The results of this Study were obtained as follows ; 1. NSS showed significantly cytotoxicitic effects of cancer cell lines, did not show cytotoxicitic effects of lymphocytes. 2, Proliferation of lymphocytes in L1210 cells transplanted mice did not effects by NSS. 3. NSS inhibited significantly the proliferation of L1210 cells in L1210 cells transplanted mice. 4. NSS improved significantly the blood count in Ll210 cells transplanted mice. 5. NSS increased significantly th body weight in sarcoma-180 cells transplanted mice. 6. NSS dereased significantly the tumor weight in sarcoma-180 cells transplanted mice. 7. NSS prolonged significantly the survival time in sarcoma-180 cells transplanted mice.

N/A Investigations were made on the population structure, sex ratio, growth, and recruitment patterns of Leptochela sydniensis in the southwestern coastal areas of Korea, between May 2000 and December 2001. Spawning period, fecundity, brood loss, reproductive output, and size at sexual maturity also were examined. The results of the sex ratio showed that females were more numerous than males during the overall study period. Parameters of growth were estimated using the modified von Bertalanffy growth function (VBGF) model incorporating seasonal variation into growth. Females grew somewhat faster and reached a larger size than males (L_(∞)=12.80 mm CL and K=0.70 yr^(-1) for females, and L_(∞)=12.08 mm CL and K=0.69 yr^(-1) for males). The structure of recruitment patterns obtained by the FiSAT program indicated one normally distributed group. Based on the occurrence of ovigerous females and the gonadosomatic index (GSI), the main spawning season was from June to August. Analysis of covariance indicated that brood loss was not observed during the incubation period. The size at which 50% of females are mature is estimated as 5.48mm CL.
