BACKGROUND: Tension headache means contraction headache or oppressive headache in bilateral occipital-cervical part or whole head. Its pathogenesy bas not been completely known yet, which may be related to many factors and the conventional therapy is drug heteropathy but the effects are different, especially on patients with chronic disease and side effects will be induced by long-time intake of drugs.OBJECTIVE: To explore the curative effect of oral negative pressure on patients with tension headache and its mechanism of ameliorating microcirculation disturbance.DESIGN: Case-control observation.SETTING: Department of Pathophysiology of Hebei North University.PARTICIPANTS: Twenty patients with tension headache in the Department of Neurology, First Affiliated Hospital of Hebei North University from December 2001 to June 2002 including 12 females and 8 males,aged 18-28 (mean 23.4) with the disease course of 1-6 years, were randomly divided into therapeutic group and control group with 10 patients in each group.METHODS: The oral negative pressure instrument was applied. Put the negative pressure exerting equipment in the optimal position of mouth, adjusted the negative pressure to (0.05±0.01) MPa. The therapeutic time was 10 minutes each time (5 minutes for the first time) once a day with the time fixed. There were 5 days in one course and totally 3 courses. Put the negative pressure exerting equipment into mouth of patients in the control group for 10 minutes each time without exerting negative pressure. Quantitative evaluation on pain was performed with visual analogue scale (VAS)method, excellent as the VAS score decreased above 70%, effective as the VAS score decreased between 30% and 70%, invalid as the VAS score decreased below 30%. XTL- Ⅱ type microcirculation micro-television system was used to observe the changes of nailfold microcirculation by magnifing 260 times. The first row nailfold of left ring figure was checked conventionally, state of microvessel, micro-bloodstream and peri-loop were recorded and degree of microcirculatory disturbance was quantitatively analyzed according to TianNiu 's weighing integral method.MAIN OUTCOME MEASURES: The therapeutic effect after three courses and results of microcirculation observation.RESULTS: Totally 20 included patients were involved in the analysis of results. VAS scores of 7 patients in the therapeutic group decreased above 70% (70%), while no patient in the control group; VAS scores of 2 patients in the therapeutic group decreased from 70% to 30% (20%) and one patient in the control group (10%); VAS scores of one patient in therapeutic group decreased below 30% (10%) and nine patie nts in the control group (90%). Negative pressure could obviously ameliorate the microcirculation disturbance and enable it to recover from moderate before treatment to nearly normal with the total score decreased from (4.18±0.68) points to (1.97±0.41) points (P < 0.01).CONCLUSION:Oral negative pressure has a significant curative effect on patients with tension headache. Its mechanism may relate to the improvement of microcirculation and the adjustment of nervous functional disturbance.

AIM: To observe the changes of morphology, the activity of myeloperoxidase (MPO) and membrane pump activities of spleen tissue in acute renal failure (ARF) rabbits, and to inquire into the role of spleen on pathogenesis of immune function disorders during ARF. METHODS: 42 rabbits were divided into control group, HgCl_2 group and glycerinum group. The ARF model was established by hypodermic injection of 1% HgCl_2 at dose of 1.3 mL/kg in HgCl_2 group, intramuscularly injection of 50% glycerinum at dose of 10 mL/kg in glycerinum group, respectively, and the animals were divided into the 12 h, 24 h, 48 h secondary groups (6 rabbits each group). At different time points, the rabbits were cannulated to facilitate the collection of blood sample to examine the biochemical indexes of renal function. The spleen microscopic sections were prepared for observing the morphology. The spleen homogenate was made for determining the activities of MPO and membrane pumping. RESULTS: Pathological sections of spleen showed that the different degree of congestion was found and spleen trabecula was increased in two model groups at multiple-time points. The MPO activity of spleen homogenate in HgCl_2 group and glycerinum group at all time points were obviously higher than that in control group, and at 24 h, the MPO activitie in two model groups was significantly increased than that in the same group at 12 h and 48 h. The activities of Na~+-K~+-ATPase, Ca~(2+)-ATPase, Mg~(2+)-ATPase, Ca~(2+)-Mg~(2+)-ATPase of spleen homogenate in two model groups at multiple time points were significantly lower than those in control group. Following ARF development, the ATPase activitie in two model groups at 48 h was lower than that at 12 h except the Mg~(2+)-ATPase in glycerinum group. CONCLUSION: Spleen as an immune organ has histological damage, arrest of polymorphonuclear neutrophils and dysfunction of membrane pump during the development of ARF in rabbits, leading to immune disorders.
