  • The effects of acetic acid fermented juice prepared with submerged culture media of Antrodia camphorata mycelium (AJA: pH 3.2, acidity 2.0, Brix degree 3.2) on blood glucose levels and serum lipid profiles of rats in which diabetes was induced with streptozotocin (STZ) were investigated. Rats were divided into normal controls (NC), diabetic controls (DM), and groups receiving diluted (1:1, with water) AJA (A1) and undiluted AJA (A2). The volume of liquid given to both A1 and A2 animals was 0.5 mL/100 g body weight. In the A1 and A2 groups, compared with the DM group, polyphagia, liver enlargement, and weight loss caused by diabetes were considerably alleviated, but did not attain the levels of NC group rats. In the A1 and A2 groups, the levels of blood glucose were 17.1% and 28.2% lower than in the DM group. There was no significant difference in the levels of fructosamine between the DM and A1 group, but the A2 group had a level 16.3% lower than the DM group. In the A1 and A2 groups, compared with the DM group, serum triglyceride levels decreased by 44.1-48.0%, serum total cholesterol by 24.0-31.1%, and serum LDL-cholesterol by 25.2-51.1%. The level of HDL-cholesterol in A2 animals rose by 45.9% compared to NC rats. The results show that AJA may be a useful beverage for diabetes patients, offering both antihyperglycemic activity and improvement in levels of serum lipids.

  • CJ-50005 is a hepatitis A vaccine which is prepared by formalin inactivation of the HM175 virus cultured in human diploid MRC-5 cells. The general pharmacological properties of CJ-50005 were evaluated in various animals and in vitor system. CJ-50005 at the doses of 0.025, 0.25 and 0.75 $\mu\textrm{g}$/kg, i.m. had no effect on general behavior in mice, chemo- and electro-convulsions in mice, writhing syndrome induced by acetic acid in mice, the barbital sleeping time in mice, body temperature in rats, charcoal meal propulsion in mice and urine and electrolytes excretion in rats. In anesthetized dogs, CJ-50005(0.25 and 0.75 $\mu\textrm{g}$/kg, i.v) did not alter the respiratory rate, blood pressure, heart rate, femoral blood flow and ECG. In in vitro experiment, CJ-50005 at the concentration up to 0.02 $\mu\textrm{g}$/ml did not produce any changes in the contractions of the isolated ileum of guinea pigs caused by acetylcholine, histamine or $BaCl_2$. Since these pharmacological effects of CJ-50005 were observed at dose much greater than those in clinical use (approximately 0.025 $\mu\textrm{g}$/kg, i.m.), it is likely that this vaccine may be relatively free of undesirable effects in clinical practice.

  • Protocols for in vitro conservation was developed for Coleus forskohlii. Plants maintained both in field served as explant source. Shoot tips and single node cuttings were used to optimize protocols for in vitro multiplication. MS basal medium supplemented with $0.54\;{\mu}M$ naphthalene acetic acid (NAA) and $8.87\;{\mu}M$ benzy-ladenine (BA) induced multiple shoots in shoot tips and nodes. Shoot multiplication was amplified with a gradual decrease of BA concentration, leading to its final omission after 4 months. Concomitant rooting on multiplication media enabled successful establishment extra vitrum. For in vitro conservation studies, experiments were carried out with 2-3 week maintained in vitro plants under standard and reduced culture conditions (SCC, RCC). In vitro plants could be successfully conserved in full strength MS medium (FMS) under SCC for 6 months without subculture with full potential to regenerate, producing viable shoots and nodes. The root production remained unaffected due to conservation, showing high rooting activity in mannitol and low temperature treatments. Preset low temperature (15 and $10^{\circ}C$) and reduction in media constituents does not appear to favour conservation, although the former accomplished conservation levels equal to (FMS) under SCC.

  • Prickly pear(Opuntia ficus-indica var. saboten Makino, Cactaceae) is a tropical or subtropical plant, which is widely used as folk medicine for burned wound, edema and indigestion. Screening on the biological properties of the fruits(OFS-Fr) and stems(OFS-St) of the plant was carried out to prove the pharmacological significance. By hot plate and acetic acid-inducing writhing methods, significant analgesic effects of OFS-Fr and OFS-St were found in mice and anti-edemic effect was observed in carrageenin-induced inflammatory rats. However, the extracts showed no significant actions on central and autonomic nervous system and blood circulatory system, which imply no toxic effects to animal.

  • Prostaglandins biosynthesis and nitric oxide production have been implicated in the process of inflammation. In this study we investigated on the effects of ethyl acetate extract of Angelica Koreana Radix (EAKR) on the activities of prostaglandin $E_2\;(PGE_2)$, proteoglycan (PG) degradation and nitric oxide synthase (NO) in inflammation cytokines-activated rabbit articular chondrocytes. EAKR exhibited inhibitory activities on NO production and $PGE_2$ production as $73.08\%\;and\;89.49\%$, respectively at $20{\mu}g/ml$ and inhibited the degradation of PG in a concentration-dependent manner Zelatin zymography analysis demonstrated that EAKR significantly inhibited MMP-2, 9 expression in chondrocytes. In vivo, EAKR was shown to have inhibitory effects on acetic acid-induced pain. This study suggests that modulation of $PGE_2$, NO, PG degradation and MMP-2, 9 by EARK may be important in the prevention of inflammation and osteroarthritis.

  • This study was conducted to investigate effects of Dansambohyultang on serum gastrin, secretin release and CNS in rats and mice. One group of seven rats was intactly in normal condition, the other group of seven rats was respectively heated, starved, and stressfully immobilized. The third group of seven rats was provided with Dansambohyultang before the stress, and the forth one after the stress. And, gastrin concentration and secretin concentration were measured. Mice were studied with regard to convulsion time, total sleep time and analegic effects on cental nerve system. The results were as follows: 1. Gastrin concentration was significantly decreased, and secretin concentration was significantly increased. 2. Analegic effect by acetic acid method was recognizably observed. 3. Effect of total sleep time done by pentobarbital-Na was recognizably observed. 4. Anti-convulsion effects induced by strychnine, picrotoxin and caffeine were recognizable. It is inferred from above results that Dansambohyultang inhibits gastin release, stimulates secretin release and palliate the pain.

  • The present study was undertaken to evaluate the anti-rheumatoidal arthritis effect of the R. verniciflua heartwood extract, its EtOAc fraction, and its primary flavonoids, sulfuretin and fustin. All test samples showed variably significant inhibitory effects on hind paw edema and trypsin inhibitor activity induced by Freund's complete adjuvant reagent (FCA reagent), and on vascular permeability caused by acetic acid. Treatment with 10 mg/kg (i.p.) sulfuretin for seven days inhibited edema formation by 54.2$\pm$3.0%. Test samples, especially sulfuretin, shifted the values of biochemical parameters such as serum-cholesterol, serum-triglyceride and serum-total protein toward the normal and restored the numbers of leucocytes and platelets. These results suggest that the heartwood of R. verniciflua reduces immunological injuries caused by FCA reagent provides evidence that suluretin is an active anti-rheumatoid arthritis agent.

  • Ribes fasciculatum (Saxifragaceae) has been widely used as a traditional medicine for the treatment of cough, antidote, cold, lacquer poison, and sore throat. In the present study, we evaluated the anti-nociceptive effects of ethyl acetate fraction of Ribes fasciculatum (ERF) in mice. Test results of tail-immersion test and hot plate test revealed that the ERF had strong anti-nociceptive activities on thermal nociception in a dose dependent manner, indicating ERF's anti-nociception on the central pain. Moreover, the acetic acid-induced chemical nociception was also significantly reduced by ERF treatment. This result shows that ERF may also work on the peripheral pain. We further performed formalin test to confirm ERF's anti-nociceptive properties and found that pain responses were significantly decreased by ERF treatment. Interestingly, in the combination test with naloxone, the analgesic activity of ERF was not changed, indicating that the opioid receptor was not involved in the ERF-mediated anti-nociception. These results indicate that ERF might be possibly used as a painkiller for the treatment of nociceptive pains.
