The aim of the present study was to investigate the effect of Palmiwon on the type 1-prediabetic models induced by streptozotocin (STZ) in RINm5F cells and HIT-T15 cells. Palmiwon increased the cell proliferation and insulin release when pre- and post-treated for the STZ-exposed pancreatic beta cells. The cell proliferation and insulin release of these beta cells were measured by $^3$H-thymidine uptake and RIA, respectively. We also analyzed nutrients such as sugars, fatty acid and amino acids and minerals containing in Palmiwon using by gas chromatography, amino acid analyzer and AA spectrometer, respectively. Palmiwon seems to have protective and recovery properties on the prediabetic model in cellular level, which were ascribe to various nutrients and minerals containing in Palmiwon. From these results, it could be suggested that Palmiwon may be available as preventive and therapeutic prescription of type 1 diabetes mellitus.

In order to investigate the usability of PALMIWON as antidiabetic immuno-modulating prescription for Insulin-dependent diabetes, we studies the effects of PALMIWON on immune cell and ${\beta}-cell$. U937 was used as the model of immune cell and RINm5F as the model of ${\beta}-cell$. The effects of PALMIWON was measured by cell viability in terms of MIT assay. As a result, PALMIWON and the compositional drugs showed the different effects m immune cell and ${\beta}-cell$. Cell viability of U937 was significantly decreased wheras that of RINm5F was no significantly difference between drug treated group and control, or significantly less reduction compared with U937. It implies that PALMIWON is useful as immunotherapeutic agents in the prevention and therapy of type 1 diabetes.

PALMIWON is composed of 8 oriental herbs which has been known to show some pharmacological effects in kidney, blood vessels and immune systems, and used for the treatment of kid ney disease, hypertension, nervous disease and diabetic mellitus in the Orient for a long time. Based on our previous report that PALMIWON showed different effects on immune cells and ${\beta}$-cells, the immunoreactivity of ICSA (Islet Cell Surface Antibody) with ${\beta}$-cell (RINm5F) and the cell proliferation and function of interleukin-1${\beta}$ damaged ${\beta}$-cells in the presence of PALMIWON were examined. It was observed that PALMIWON significantly inhibited the immunoreactivity of ICSA with ${\beta}$-cell, and markedly increased cell proliferation and insulin release of interleukin-1${\beta}$ damaged ${\beta}$-cells.

It has been known for a long time that Palmiwon water extract can be prescribed for the treatment of deficiency of Yang in oriental medicine. But the exact mechanism of it has not been Known yet. In the present experiments, it was attempted to explain the effect of Palmiwon water extract on the serum Hormone level in rabbits and the antifatigue in mice. Palmiwon water extract oral intake showed a increase of serum hormone level in rabbits and the effects of the antifatigue in mice. The results obtained were as follows. 1. The administration of this medicine was observed to cause continuously a significant increase of the testosterone content in the serum from the 7th day to the 21th day. 2. The estradiol centent in the serum, as compared with the control experiment, was seen to increase significantly by the administration of this medicine from the 7th day to the 21th day. 3. The LH and FSH content in the serum, as compared with the control experiment, indicated a tendency toward an increase by the administration of this medicine from the 7th day to the 21 th day, but with no significant difference. 4. In the effect to Palniwon on the antifatigue in mice, swimming time was prolonged in both sample A, B groups than control group, and significance revealed in both sample A, B groups. These data suggest that Palmiwon water extract can increase serum hormone level and that it can have therapeutic effectiveness to the antifatigue.
