Prolactin (PRL) is a pituitary hormone involved in various physiological processes, including lactation, mammary development, and immune function. To further investigate the in vivo and comparative endocrine roles of PRL, mouse PRL cDNA fused to the cytomegalovirus promoter, was introduced into muscle by direct injection. Previously we studied the function of rat PRL using the same protocol. PRL mRNA was detected in the muscle following injection by RT-PCR and subsequent Southern blot analysis. PRL was also detected and Western blot analysis revealed a relatively high level of serum PRL. In the pCMV-mPRL-injected female mice, the estrous cycle was extended, especially in diestrus stage and the uterus thickening that was shown in normal estrous stage was not observed. In the pCMV-mPRL-injected male mice, new blood vessels were first found at 5 weeks of age and fully developed blood vessels were found after 8 weeks in the testis. The number of Leydig cells increased within the testis and the testosterone level in serum was observed high. Finally, the number of white blood cells (WBCs) increased in the pCMV-mPRL-injected mice. The augmentation of WBCs persisted for at least 20 days after injection. When injection was combined with adrenalectomy, there was an even greater increase in number of WBCs, especially lymphocytes. This increase was returned normal by treatment with dexamethansone. Taken together, our data reveal that intramuscularly expressed mouse PRL influences reproductive functions in female, induces formation of new blood vessels in the testis, and augments WBC numbers. Of notice is that the Leydig cell proliferation with increased testosterone was conspicuously observed in the pCMV-mPRL-injected mice. These results also suggest subtle difference in function of PRL between mouse and rat species.

This study was performed to investigate the modifying effect of the general (GPA) and the fermented pilose antler (FPA) on experimental hepatocarcinogenesis and Natural Killer cell activity in rats. Specific pathogen free, 5-week male Sprague-Dawley rats were divided into four groups. To induce hepatocarcinogenesis, diethylnitrosamine (DEN, 200 mg/kg, i.p.) was used as a tumor initiator and was given in a single dose at experimental onset. All rats were given a partial hepatectomy (PH) at 3 weeks after experimental onset. Sodium phenobarbital (PB, 0.05% in diet), GPA (0.075% in diet) and FPA (0. 075% in diet) were given from 2 to 8 weeks. Group I of the initiation control group was only given DEN. As initiation-promotion group, Group II was given DEN and then PB. Group III and IV were given DEN-PB-GPA and DEN-PB-FPA, respectively. In hematological analysis, as compared with Group I. the number of white blood cells were significantly increased in the GPA (p<0.01) and the FPA treated group (p<0.05), respectively. Natural killer (NK) cell activity by flow cytometer (FCM) analysis was higher in group of treated with the GPA (35%) than that of the FPA (27.5%), but not significant. Result of the immunohistochemical staining of the glutathione S-transferase placental form (GST-p) indicated that the number of and area of the pre-neoplastic lesions was not significantly changed in Group III and IV compared Group II, respectively. In conclusion, the GPA and the FPA treatment significantly increased the number od WBC in peripheral blood, but the enhancing NK activity and the modifying effect on the experimental hepatocarcinogenesis were not observed.

Effects of endosulfan (EN), an insecticide, and bleomycin (BL), an antibiotic, on the body weight in the normal mice, and the in vivo cell growth, tumor weight, and hematological parameters of the Ehrlich ascites carcinoma (EAC) cell-bearing Swiss albino mice Mus musculus were evaluated. EN and BL were respectively administered orally and intraperitoneally to the experimental mice; the control group consisted of EAC cell-bearing untreated mice only. EN reduced the body weight in normal mice, whereas BL resulted in a steady body weight compared to the control. EN increased the EAC cell count significantly by reducing the growth of normal viable cells. In contrast, BL reduced the cell count by increasing the proportion of viable cells in the body. The tumor weights induced by EN were significantly higher than those of the EAC control and the BL-treated animals. In comparisons with the control and the BL mice, hematological parameters such as hemoglobin (%) and the number of RBC and lymphocytes were lowered, while counts of WBC, neutrophils, and monocytes were elevated after EN treatments. These results show that BL is capable of reducing the EN-induced neoplastic and haematological alterations in the mice under laboratory conditions.

In order to investigate the of effects of nalbuphine on immune system in mice, we examined the various immunological parameters. After single oral administration of nalbuphine (130, 260, 390 mg/kg, i.p.) to female ICR mite, the weights of bodies and organs (thymus, spleen, liver, kidney), and hematological parameters were examined on day 2, 4, 6, and 8. The increased rate of body weight, relative weight of organ, and hematological parameters in nalbuphine -treated groups, were not significantly changed when compared with control group. However, number of WBC was decreased by the treatment of nalbuphine. To assess the effects of nalbuphine on humoral immune responses, splenic IgM plaque forming cell (PFC) and serum IgM were assayed. When nalbuphine wat administered after immunization with SRBC, but not before immunization, splenic IgM PFC and ,serum IgM level against SRBC were significantly lowered in a dole -dependent manner. These results indicate that the suppressive effects of nalbuphine on primary humoral immune response may be dependent on the timing of its administration relative to the initial antigenic sensitization.

This study was performed to determine the toxic effect of DA-3030(granulocyte-colony stimulating factor, G-CSF) in beagle dogs. DA-3030(G-CSF) was injected intravenously at doses of 115 $\mu\textrm{g}$/kg/day, 11.5 $\mu\textrm{g}$/kg/day and 1.15 $\mu\textrm{g}$/kg/day seven days per week for 28 days. After completion of the treatments, the dog were necropsied. The number of dead animal was zero in all groups. No specific clinical sign was found, either. In hematological results, WBC was significantly increased dose-dependently in treated groups. In histopathological findings, megakaryocyte and rubricyte were found in the liver and spleen at the dose of 115 $\mu\textrm{g}$/kg/day. Therefore, we could find the extramedullary hematopoiesis was increased. Megaka yocyte and rubricyte were increased in bone marrow, too. In conclusion, those signs were estimated the pharmacological effect of DA-3030(G-CSF). According to the results, non toxic dose of DA-3030(G-CSF) was higher than 115 $\mu\textrm{g}$/kg/day.
