BACKGROUND: The dangerous factors of cerebrovascular disease are also those of vascular dementia (VD). Stasis and retardation of cerebral channels is the basic pathogenesis of VD, kidney-qideficiency is the important pathogenic foundation of VD and therefore the most effective treatment is to stimulate blood circulation to remove stasis, tonify the kidney and improve intellegence.OBJECTIVE: To observe the clinical effects of kangnaoling, a granule traditional Chinese medicine, on the patients with VD. DESIGN: Randomized controlled observation. SETTING: Affiliated Hospital of Shandong University of Traditional Chinese MedicinePARTICIPANTS: Totally 60 patients with VD were selected from Affiliated Hospital of Shandong University of Traditional Chinese Medicine, Zibo City Traditional Chinese Medicine Hospital and the Clinic of Handan Traditional Chinese Medicine Hospital in Hebei Province from May 1998 to October 2001. The patients were randomly divided into experimental group (n=40) and control group (n=20).METHODS: Experimental group: Kangnaoling granules (chief ingredients: gingko leaf, epimeddium and chuanxiong rhizome, etc.) were taken orally,1 pack/time, three times per day. Control group: Naofukang was taken orally, 0.8 g/time, three times per day. The two groups took the medicine both for two months as a course. According to the integral of symptoms and the score in all kinds of scales before and after treatment, the patients were classified into 4 grades: clinically-controlled, remarkable effective, effective and ineffective or worse. Clinically-controlled: The main symptoms in the patients, on the whole, returned to normal. They could well-perform orientation, correctly answer questions, take care of themselves and resume ordinary social activities; remarkable effective: Part of the main symptoms in the patients returned to normal. They could take care of themselves, basically perform orientation, correctly answer questions although their reaction was ordinary. Effective: The main symptoms in the patients were relieved or partly disappeared. Generally, they could take care of themselves, correctly answer questions but their reaction was still slow and had dysfunction in mentality and personality. Ineffective: the main symptoms in the patients were not bettered, even worse. The neuropsychology and cognitive ability of the patients were determined with Mini-Mental State Examination (MMSE) and Hasegawa Dementia Scale (HDS) (total score: 30 points), and the daily living ability of the patients was detected with Functional Activities Questionnaire (FAQ) (It was defined as normal when the score was ≤5 points, and the lower the score was, the better the effect was). MAIN OUTCOME MEASURES: ① The comparison between the two groups in the clinical effect after treatment. ② The comparison between the two groups in the score of MMSE,HDS and FAQ before and after treatment. RESULTS: All the 60 patients were involved in the analysis of results, no one lost. ① The comparison between the two groups in the clinical effect after treatment: The remarkable effective rate was higher in experimental group than in control group (78%, 50%). ② The comparison between the two groups in the score of MMSE, HDS and FAQ before and after treatment: in experimental group, the score of MMSE and HDS was all higher after treatment than before treatment (17.03±5.58, 12.42±3.87; 20.36±6.60,14.73±4.68) while the score of FAQ was lower after treatment than before treatment (10.64±4.58, 15.38±3.37). In control group, the score of HDS was higher after treatment than before treatment (16.82±3.95, 13.20±3.12)while the score of FAQ was lower after treatment than before treatment (11.16±1.06, 14.10±2.15). And the score of HDS was higher in experimental group than in control group after treatment, there was significant difference (P < 0.05).CONCLUSION: Kangnaoling granules and naofukang all have the effect in improving the intellegence of the patients with VD while kangnaoling granules have better clinical effect.

BACKGROUND: Naomaitong injection is a Chinese herbal compound preparation for treatment of ischemic cerebral vascular disease, acting on resisting calcium overload, regulating the imbalance between thromboxane (TXA) and prostaglandin (PG) and blocking lipid peroxidation mediated by free radical so as to protect cerebrum.OBJECTIVE: To observe the effects of naomaitong injection on water and Ca2+ contents, activity of superoxide dismutase (SOD), levels of lipid peroxide (LPO), 6-keto-PG lα and TXA, and compare it with danshen injection.DESIGN: Randomized control experiment was designed.SETTING: Experimental Center of Chengdu University of Traditional Chinese Medicine.MATERIALS: The experiment was performed in Experimental Center of Chengdu University of Traditional Chinese Medicine from October 1997 to February 1998, in which, 72 healthy male Wistar rats were employed, rangroup: Abdominal injection was done with physiological saline 1.67 mL/kg,group): Abdominal injection was done with compound danshen injection groups (naomaitong No.1, No.2 and No.3 groups): abdominal injection was done with naomaitong injection 3.33, 1.67, 0.84 mL/kg successively,twice/day.METHODS: Totally 48 hours after medication, under anesthetized state,the rats in every group were sacrificed to collect brain tissue. The two hemispheres were cut into two pieces from the middle. One of them was prepared into brain tissue homogenate at low temperature. Radioimmunologic analysis method was used to measure 6-keto-PG 1o and TXA B2 levels so as to evaluate the balance between PG and TXA systems. The modified pyorgallol autoxidation and thiobarbituric acid (TBA) colorimetric method were applied to determine SOD activity and LPO level respectively so as to evaluate lipid peroxidation mediated by free radical. The dry and wet weights of other piece were weighed immediately on electronic scale and the water content of brain tissue was calculated to evaluate brain edema. Atomic absorption spectrophotometry (AAS) was used to determine Ca2+content in brain tissue so as to evaluate calcium overload.tissue of rats in every group.content in brain tissue of rats in every group: That in model group was higher remarkably than normal group [(82.27±1.32)%, (77.24±1.36)%;(267.47±15.69), (37.55±13.23) μg/g, P ＜ 0.01]. The water contents in 4 treatment groups were decreased of various degrees. The effect in No.1 group was the strongest [(78.74±1.41)%] and that in danshen group was the weakest [(81.45±1.52)%]. Ca2+ content in danshen group was decreased of various degrees, indicating dose-effect dependence, but, which was near to ty and LPO level in brain tissue of rats in every group: SOD activity in model group was lower remarkably than normal group [(86.18 ±3.17),(131.86±4.67) μkat/g, P ＜ 0.01]. After treated with naomaitong of 3 dosages, that was all improved, indicating dose-effect dependence (P ＜ 0.01). The effect of No.1 group was the strongest [(119.02±4.00) μkat/g],SOD activity in danshen group was near to model group (P ＞ 0.05). LPO level in model group was higher than normal group [(52.46 ±3.25),(32.29±2.23) μmol/L, P ＜ 0.01]. LPO level of every treatment group was lower significantly than model group and the therapeutic effects of No. 1, 2,3 groups were superior to danshen group [(35.68±2.86), (41.54±2.47),1α and TXA B2 in brain tissue of rats in every group: Content of 6-ketoPG 1α in brain tissue of model group was lower remarkably than normal group (P ＜ 0.01). That was improved in all of 4 treatment groups, in which,the therapeutic effects of No.1, 2, 3 groups were superior to danshen group [(43.84±2.98), (35.01±4.32), (29.97±3.81), (22.89±3.64) ng/g, P ＜ 0.01].TXA B2 content in brain tissue of model group was higher remarkably than normal group (P ＜ 0.01). After treatment, the 4 treatment groups lowed significantly TXA B2 content in brain tissue compared with model group,indicating dose difference. That in danshen group was lower than No. 1, 2,3 groups [(40.58±1.34), (32.85±1.43), (34.31±1.39), (37.27±1.52) ng/g, P ＜0.01].CONCLUSION: Naomaitong injection alleviates brain edema, resists calcium ion, regulates imbalance between TXA and PG systems, improves activity of anti-oxidase and is against injury of free radical so as to protect the structure of brain tissue and achieve therapeutic effects, indicating a certain dose-effect relationship. The effect of naomaitong injection is superior to that of compound danshen injection.

Objective To study the effects of living environment conditions and animal-animal interaction on the blood hormone levels and psychological behavior in Chinese tree shrews .Methods Chinese tree shrews were raised in ca-ges of different space sizes or were administered reserpine for 15, 30, 60, 120, 180 days, respectively.Then the animals were anesthetized by ether inhalation , and blood samples were taken from the heart to detect the levels of blood testosterone (T), estradiol (E2), endothelin (ET), adrenaline (A) and noradrenaline (NA) by radioimmunoassay (RIA).Results 1.Chinese tree shrews were bred in large cage (D1group) or small cage (X1 group) for 15, 30, 60, 120, 180 days, re-spectively.Compared with the animals bred in the large cage (D1 group), the level of blood testosterone (T) was signifi-cantly reduced (P<0.01), and the levels of adrenaline , noradrenaline and endothelin were significantly increased in the small cage group (P<0.01 for all).2.The animals raised in small cages in close neighborhood with large cages for 15, 30, 60, 120, 180 days, respectively.The levels of testosterone, adrenaline and noradrenaline in the large cage group (X2 group) were significantly higher than those of the small cage group (X1 group) (P<0.01 for all).3.The adrenaline and noradrenaline levels were significantly lower in all the reserpine groups (P<0.01 for all).4.The animals bred in small cages (X1 group) and in small cages in close neighborhood with large cages showed sudden loss , reduced appetite, testicu-lar atrophy , penile prolapse and stress symptoms .The animals of the reserpine groups appeared gentle temperament , signif-icantly reduced activity and reduced appetite .However , after stopping the reserpine administration and feeding them in large cages , the animals gradually returned to normal behavior .Conclusion Both animals living environment conditions and animal-animal interaction may cause changes of blood hormone levels and psychological behavior in Chinese tree shrews.

A method was proposed for the separation and determination of paraffin waxes in food by HPLC-evaporative light scattering detection (ELSD). A normal-phase column was used to separate nonparaffinic and paraffinic materials without resolving the latter into individual components. The t-test method was adopted for the evaluation of mean difference between response factors of n-alkanes in paraffin waxes on ELSD detector. No mean difference was obtained between response factors, which can be used for quantitative determination of paraffin waxes in food. The determination results obtained by HPLC-ELSD were compared with those by GC-MS. The linear range for the determination of paraffin waxes was in the range from 10 to 500 mg/L with a correlation coefficient of 0.9988, and the limit of detection was 1.0 mg/L. With the spiking level of 10, 50 and 100 mg/kg, the recovery ranged from 84.6% to 105.4% and the relative standard deviation ranging from 5.4% to 7.2%. The proposed method is simple, fast and sensitive.

Objective To study the effect of low frequency electrical stimulation on blood hormone levels in differ -ent animals.Methods At 12 h, 24 h and 36 h after low frequency electrical stimulation to Chinese tree shrews , Wistar rats, and BALB/c mice, respectively, the blood noradrenaline (NA) and endothelin (ET) levels were determined by ra-dioimmunoassay ( RIA) .Results The blood NA and ET levels of electrical stimulation group were significantly higher than that in the control group (P <0.01).At 24 h after reserpine treatment, the same electrical stimulation was given. The NA, ET levels were significantly decreased compared with that in the electrical stimulation group (P<0.05 to 0.01). Different animals responded to the same electric stimulus differently , following the order of Chinese tree shrews >Wistar rats >BALB/c mice.Conclusions Low frequency electrical stimulation can promote the release of noradrenaline and en -dothelin in Chinese tree shrews , Wistar rats and BALB/c mice.Reserpine can reduce the stress induced by low frequency electric stimulation to the body .
