On rat, among 4 these herbal medicine plants, only Rehmania flutinosa does not decrease significantly the blood sugar level with the oral doses of 1000-1500 mg/kg body weight and with intraperitoneal doses of 200-300mg/kg. Oral use of Anemarrhena asphodeloides and Angiopteris evecta decreases blood sugar at the doses of 100-1.500mg/kg. Intraperitoneal use of the doses of 200-300mg/kg Anemarrhena asphodeloides, Angiopteris evecta and gynoitema pentaphyllum lower glycemia by above 25% in comparison with the pretreated level.

Cryophylisat powder of ethanolic fluid extract of Smilax glabra with the oral dose of 1.25g and 2.5g/kg of body mass (5-10 times of active dose on hypoglycemic effect was administered in rabbit in 15-30 days continously. These doses did not influenced on the body mass, the hematologies indices as well as the functional indices of lever and kidney. However, in microscopic image, there are some degenerative mainfestations of low levels of liver cells among two groups using the studied preparation.

Cryophylisat powder of ethanolic fluid extract of Smilax glabra (SG) was administered orally on mouse with a single dose of 1g/kg of body mass. Hypoglycemic effect exerted with 10.58% approximatively. Continous use of 7 days of this dose increased the hypoglycemic action. Oral SG effects manifested lately with less level than injectable SG. Apart from the increase of synthetization capacity of glycogene, SG promote the sensitivity of the tissues to insuline.

The 1:1 aqueous extract of Radix Psychotria morindoides Hutch – Rubiacease with an oral dose of 10g/kg body weight of rat: Has no acute and anti-inflammatory effect on carrageenin – indecued edema in hind paw, but it reduces the asbestos induced granuloma as a subchronic inflammation medel. Increases the excretion of urine up to 83% at the sixth hour after drug ingestion. DL50 of the aqueous extract could not be determined because of its very low toxicity.

A survey has been carried out at 36 communes from 9 provinces represented for the whole country from January to March 1996 in order to evaluate the drug sale, the drug management in commune health stations and in private pharmacies. The results indicate that there are also many limitations and weaknesses in performance of certain regulations of MOH. The authors have proposed some procedures to improve these limitations.

Each PDE have isogenies (PDE 4A, PDE 4B, PDE 4C, and PDE 4D), which had different level in tissues. A cell can contain one or more DPE type. When agent (or drug) specifically and inhibited isoenzym, it will have specific effect on proteinkinase. The PDE4 and PDE3/4 compound inhibitive drugs have effects at the same time to relax trachea and anti-inflammatory. Viagra is PDE5 selective inhibitor, more important than PDE 2-3-4 with 1000 times, PDE 1 with 80 times, PDE 6 and PDE 7 with 10 times. This agent have many in vessels and cavernosum corpus. It plays role of break dow GMPv, but it depends on NO.

CoX-2 or prostaglandin GH synthetase-2 is an enzyme which has induction, especially in the inflamatory reactions. The inflamatory stimulations activate the CoX-2 of monocytes, macrophages, cells of synovial membrane to synthesize prostaglandin which induce the inflamatory reactions. The non- steroid anti- inflamatory drugs inhibit the CoX-2 so they have anti- inflamatory effects. However, they also inhibit CoX-1 which induce some side effects such as gastrointestinal and kidney accidents, haemorrhage and hypersensitivities. The selective CoX-2 inhibitors have some properties: long half elimination life, easier uptake by oral; the same pharmacokinetics in both elderly and children and uncommon side effects (0.1 -1% treated cases).

The influence of some medications including medicaments originated plant on the liver and kidney functions and histologic changes in experiemental animal is carried out. The results shows that the liver and kidney function of rabit are not affected by the doses of 10-20 fold higher than clinical doses. Conclusion: These medications can be tried on the clinical at dose of less than 1.0 g/kg of bodyweight within 2 weeks with interval of 1- 2 weeks.

Effects of aqueous extracts from the root of Morinda sp. were studied on liver injury induced by a high dose of paracetamol (acetaminophen) in rats. The results showed that the extract had a hepatoprotective effect at a dose of 10g/kg of body weight. The effect was similar to that of silymarin at a dose of 25mg/kg of body weight in terms of AST, ALT activities, total serum cholesterol and protein concentrations as well as macro-and microscopic histological studies of the liver.

Objectives: To evaluate the hypoglycemic effect of these herbal medicines' on normal mice. Methods: the ethanol extracts of these plants have been introduced intraperitoneally to mice with the dose of 500 mg/kg of body weight. The blood glucose levels were determined by one - touch glucose meter at just (0h) before and at 1h, 2h, 3h, 4h and conclusion after drug administration. Results: Lycium sinense Mill lowered the glycemia by more than 30% in comparison to that of initial level. Separia dulcis, however, caused hyperglycemia (+ 62%) at the first hour then at the 3rd and 4th hour the blood glucose was diminished with>30%. Atractylodes macrocephala did not lower the glycemia.
