On the basis of the semen analysis in 66 subjects, they were divided into six different groups: Group I consisted of 16 normal subjects with sperm counts of over 40 ${\times}10^6$/ml and motility of over 40 percent, Group II, 7 subjects with normal sperm counts, but motility of under 40 percent, Group III, 15 oligospermic patients with under 40 ${\times}10^6$/ml, Group IV 14 azoospermic patients, Group V, 10 patients with vasectomy and Group VI, 4 abnormal patients with 2 cases of hypoplastic testis, 1 case of Klinefelter's syndrome and 1 case of testis tumor. After seperation of semen into sperm and seminal plasma by centrifugation, the protein contents and the activities of hyaluronidase, ${\beta}$-N acetylglucosaminidase, ${\beta}$-glucuronidase, arylsulfatase, acrosin and azocoll proteinase in seminal plasma were measured. Vasectomy group has 30 percent less of total protein than normal group. For the comparison of enzyme activities of seminal plasma, it could be assumed that the enzymes in seminal plasma were not contaminated with the enzymes of spermatozoa by testing the enzymes of the seminal plasma from the vasectomy and azoospermic groups. It had been reported that hyaluronidase was only released from spermatozoa, however, the result obtained in this investigation showed that azoospermic and vasectomy group had high specific activities of hyaluronidase. The results indicated that hyaluronidase was not only from the testis but also from the male accessory sexual glands. Oligospermic group (Group III) showed the lowest total activity of hyaluronidase among them. The specific activities of ${\beta}$ -N-acetylglucosaminidase was high in oligospermic group (Group III) and low in vasectomy group (Group V). These results were contradictory with the pattern of hyaluronidase activities. This indicated that the spermatozoa which were stayed in epididymis would increase the activity of this enzyme. The specific activity of ${\beta}$ - glucuronidase was low in oligospermic and vasectomy groups. Group VI including testis tumor had remarkably high arylsulfatase activity. Arylsulfatase, a typical lysosomal enzyme, has been known to be released unusually large amounts from certain tumor cells. Arylsulfatase was also released with high activities from azoospermic and vascetomy group. This result indicated that this enzyme was also released from the sources other than testis. Acrosin, a proteolytic enzyme locating in the sperm acrosome, was not found throughout all the samples of seminal plasma. The activities of azocoll proteinase, a non-specific neutral proteinase was nearly identical in all the groups. This enzyme must have been released from the sources other than testis.

Anti-allergic action of each water extracts of some crude drugs was investigated in mice and rats. The activity of hyaluronidase which was used in the screening test of anti-allergic action was inhibited significantly by Amomi Semen, Asiasari Radix, Cimicifugae Rhizoma, Cinnamomi Ramulus, Glycyrrhizae Radix and Scutellariae Radix. The 48-hour homologous passive cutaneous anaphylaxis(48-hr PCA) in mouse ear was inhibited significantly by intraperitoneal(i.p.) injection of Amomi Semen, Cimicifugae Rhizoma, and ketotifen, a comparative drug of an anti-allergic action. The increase of vascular permeability induced by histamine or serotonin was inhibited significantly by i.p. injection of Amomi Semen, Cimicifugae Rhizoma, Cinnamomi Ramulus and ketotifen. In rat dorsal skin, the increase of vascular permeability which was induced by histamine, serotonin or compound 48/80 was inhibited significantly by i.p. injection of Amomi Semen, Asiasari Radix, Cimicifugae Rhizoma, Scutellariae Radix and ketotifen. Armeniacae Semen and Liriopis Tuber which had not inhibited hyaluronidase activity did not inhibit 48-hr PCA and the increase of histamine, serotonin or compound 48/80-induced vascular permeability in mice and rats. These results suggest that each water extract of Amomi Semen and Cimicifugae Rhizoma has anti-allergic action.

Objective: These studies were undertaken to evaluate the effects of the different administration duration of Morindae Radix extract solution on spermatogenic abilities such as concentration, motility and morphological normality of sperm from the testes and the activities of sperm hyaluronidase. Materials and Method: We used 8-week-old ICR mice and administered 0.3mg/g extract solution of Morindae Radix once a day for 30, 60, 90 and 120 days. The control group was administered normal saline in the same way and duration. We examined the number of total, motile and normal sperm from the cauda epididymis. We also compared the testicular tissue, especially seminiferous tubules, between the control and treated groups by histochemical methods. Finally, we observed the difference of sperm hyaluronidase activities between the control and treated groups. Results: Significant administration duration-dependent differences were observed in the concentration of total sperm, motility and normality of spermatozoa of the Morindae Radix extract solution administered groups compared to the control group. In the histological analysis of the testicular tissues, the enlargement of testicular lobe diameter and apparent vasculogenesis between testicular lobes were observed in the Morindae Radix extract solution administered groups compared to the control group. Also, the activity of hyaluronidase was significantly increased in the Morindae Radix extract solution administered groups compared to the control group. Conclusions: This study shows that the beneficial effect of Morindae Radix extract solution on the concentration, motility and morphology of sperm, the testicular tissues and the activities of sperm hyaluronidase increased the greater the duration the mice were administered it. We suggest that Morindae Radix may be useful for the treatment of male sexual dysfunction and infertility.

Hyaluronic acid (HA) is a mucopolysaccharide, occurring naturally in living organisms. It is one of the most hydrophilic molecules, so it has been known as being related to skin hydration and skin aging. The purpose of this study was to examine the effects of Cimicifuga heracleifolia ethanol extract on the hyaluronic acid synthesis and the inhibition of hyaluronidase activity. To determine cytotoxicity, hyaluronic acid synthase 2 (HAS2) gene expression, HA production and, hyaluronidase inhibitory effects, 3-(4,5-dimethylthiazol-2-ly)-2,5-diphenyl tetrazolium bromide (MTT) assay, real time - polymerase chain reaction (RT-PCR), hyaluronic acid enzyme linked immunosorbent assay (HA-ELISA), and hyaluronidase assay were used, respectively. When the Cimicifuga heracleifolia extract was treated in the HaCaT cells up to 500 ㎍/mL concentration, cytotoxicity was confirmed by the Cimicifuga heracleifolia extract at concentrations above 200 ㎍/mL. Therefore, the optimum concentration of all experiments used in this study was determined to be 200 ㎍/mL. HAS2 gene expression increased by Cimicifuga heracleifolia extract in a concentration-dependent manner at all treatment concentrations. The production rate of HA was tended to decrease at the highest concentration of 200 ㎍/mL. The hyaluronidase activity inhibition effect of Cimicifuga heracleifolia extract was very high compared to the control group. Based on these results, Cimicifuga heracleifolia extract was expected to have a moisturizing effect on human skin and special attention should be paid to the determination of the concentration of Cimicifuga heracleifolia when developing cosmetic materials using it.

Hyaluronidases enhance therapeutic drug transport by breaking down the hyaluronan barrier to lymphatic and capillary vessels, facilitating their tissue absorption. Commercially available hyaluronidases are bovine in origin; however, they pose risks such as bovine spongiform encephalopathy. The present study aimed to develop a novel, highly active hyaluronidase and assess its function. Therefore, in order to find the most efficient active hyaluronidase, we produced several shortened hyaluronidases with partial removal of the N- or C-terminal regions. Moreover, we created an enzyme that connected six histidines onto the end of the hyaluronidase C-terminus. This simplified subsequent purification using $Ni^{2+}$ affinity chromatography, making it feasible to industrialize this highly active recombinant hyaluronidase which exhibited catalytic activity equal to that of the commercial enzyme. Therefore, this simple and effective isolation method could increase the availability of recombinant hyaluronidase for research and clinical purposes.

In this study, we prepared two extracts using 1,3-butylene glycol (DBG) and ethanol (DET), with Diospyros kaki and determined the anti-oxidant, anti-aging, and whitening effects in vitro. Anti-oxidant activity was measured by DPPH and superoxide dismutase (SOD) method, and as a result, both DBG and DET extracts confirmed their anti-oxidant properties by exhibiting significant DPPH scavenging and SOD-like activities. For anti-aging activity, we measured elastase and hyaluronidase inhibition, and the inhibition of MMP-1 expression. Both DBG and DET significantly inhibited elastase and hyaluronidase activities dose-dependently, and MMP-1 expression was also reduced in both extracts. We also measured the whitening effects with tyrosinase activity and melanin production, but only DBG showed a decrease in tyrosinase. In summary, D. kaki extract has strong antioxidant, anti-aging, and whitening functions, and it is believed that it can be used as a cosmetic material in the future.

Anti-inflammatory assay was conducted on 20 kinds of traditional Indonesian medicinal herbs using soybean lipoxygenase (SLO) and hyaluronidase (HAse). Cinnamomun burmanni Bl showed highest anti-inflammatory activity. Ethyl acetate fraction from methanol extract of C. burmanni Bl bark showing high SLO inhibitory activity was isolated using silica gel-60 column chromatography. Two compounds were isolated and purified through preparative HPLC. Through analyses of UV, $^1H-NMR$, $^{13}C-NMR$, EI-MS and $FAB^+-MS$, compounds 1 and 2 were identified as coumarin and 2-hydroxy cinnamaldehyde, respectively, among which 2-hydroxy cinnamaldehyde showed SLO inhibitory activity of $IC_{50}\;=\;60\;{\mu}M$. Both compounds did not exhibit HAse inhibitory activity.

Purpose : These studies were undertaken to evaluate the effects of Allii tuberosi Semen (ATS) on the spermatogenic abilities such as concentration, motility and morphological normality of sperm from the testis and the activities of sperm hyaluronidase, testicular peroxidase and testicular catalase. Materials and Methods : We used the 8-week-old mice and administered the 0.2 ml extract solution of ATS in the different concentration (0.1 mg/ml, 1 mg/ml, 10 mg/ml and 100 mg/ml) once a day for 60 days. The control group was administered the distilled water in the same way. After the administration of each extract solution, we examined the number of total, motile and normal sperm, the activities of sperm hyaluronidase, testicular peroxidase and testicular catalase. Also we observed the histological changes of isolated testis. And we compared to the testicular tissue especially seminiferous tubules between control and treated group by histochemical methods. Results : The concentration of total sperm, the motility and normality of spermatozoa were significantly increased in ATS groups, especially in 1 and 10 mg/ml groups, compared to control group. In the histological analysis of the testicular tissues, the enlargement of testicular lobe diameter and apparent vasculogenesis between testicular lobes were observed in the ATS groups compared to the control group, respectively. Also, the activity of hyaluronidase was significantly increased in the ATS groups compared to the control group. In the antioxidant activity analysis, the activity of testicular peroxidase was significantly increased in the ATS groups compared to the control group, especially in 1 mg/ ml group. The activity of testicular catalase was increased in ATS groups. Conclusion : This study shows that ATS has the beneficial effect on the concentration, morphology and motility of sperm, the activities of sperm hyaluronidase and testicular peroxidase. We can suggest that ATS extract solution be useful for the treatment of male sexual dysfunctions and infertility.

Inhibitory effects of 200 medicinal plants on elastase activity were screened. Among the 200 plants, six plant extracts exhibited more than 65% of inhibition on elastase activity by their total methanol extracts at 1, 000$\mu\textrm{g}$/$m\ell$ as a final concentration. For six active plants including Areca catechu, Cinnamonum cassia, Myristica frograns, Curcumma longa, Alponia katsumadai, and Dryopteris crassirrhizoma, the inhibitory effects of their comsituents were examined on the activity of human leukocyte elastase, hyaluronidase and lipid peroxidation. In lipid peroxidation assay using TBA method, three of the 6 plants including Curcumma longa, Areca Catechu and Alponia katsumadai exhibited more than 70% of inhibition at the concentration of 1, 000$\mu\textrm{g}$/$m\ell$, but only one plant, Areca Ctechu showed high inhibitory effect on hyaluronidase activity. The results suggest that medicinal plants showing several biological activities may be potent inhibitors of anti-aging process on skin and that might be useful for application in cosmetics.
