The microangioarchitecture of the thalamus and metathalamus in common tree shrew (Tupaia glis) was studied using vascular corrosion cast/stereomicroscope and SEM technique. The arterial supply of the thalamus and metathalamus
was found to originate from perforating branches of the posterior communicating artery, the posterior cerebral artery, the
middle cerebral artery, and the anterior choroidal artery. These perforating arteries gave rise to numerous bipinnate arterioles
which in turn, with decreasing vessel diameters, branched into a non-fenestrated capillary bed. Venous blood from the superficial
parts of the thalamus and metathalamus was collected into the thalamocollicular vein, whereas venous blood from internal aspects
of the thalamus was conveyed to the internal cerebral vein. Some venous blood from the most rostral part of the thalamus flowed
into tributaries of the middle cerebral vein before draining into the cavernous sinus. Further, the thalamic and metathalamic
vascular arrangement was found to be of centripetal type. In addition, thalamic arterial anastomosis was rarely observed.
Thus, obstruction of thalamic blood supply could easily lead to thalamic infraction. 相似文献

Immunization with Bungarus candidus venom was performed in four rabbits at high dose (initial dose, 75 microg/kg) and low dose (initial dose, 50 microg/kg). Each dose group consisted of two rabbits; one rabbit received the venom subcutaneously (s.c.) and the other intradermally (i.d.). The venom was injected as emulsified solutions with the same volume of Freund's complete adjuvant until the 4th immunization, thereafter as plain solutions. By stepwise increments of the immunizing dose, the higher dose group received a dose of 200 microg/kg and the lower dose group 150 microg/kg after the 5th immunization, respectively. Thereafter, seven additional immunizations were performed within six months. All rabbits were sacrificed two weeks after the last immunization (12th). Antilethal activity of the immunized antisera thus obtained was determined not only with the homologous venom but also with two heterologous venoms from Bungarus fasciatus and Bungarus flaviceps. Immunodiffusion analysis was also performed with these venoms. The results obtained in this pilot trial provided useful information for production of Malayan krait antivenom at Queen Saovabha Memorial Institute. 相似文献

PURPOSE: This article aims to explore the relationship between technology and quality management for enhancing Thai hospital service quality. DESIGN/METHODOLOGY/APPROACH: The paper presents the findings of an exploratory study that investigates service quality from the customer and service provider perception. In-depth interviews were conducted with respondents in Thai hospitals. The interviews explored service-related factors that patients and service providers perceive to be important for hospital services. The first interview group consisted of professionals as internal customers in direct contact with external customers, while the second group consisted of external customers of the same hospitals. FINDINGS: The study's outcomes clearly suggest factors that make significant contribution to service quality. These factors can be categorized according to five SERVQUAL dimensions (reliability, responsiveness, assurance, empathy, and tangibility), although some factors required slightly different interpretation. ORIGINALITY/VALUE: The findings suggest that hospitals can develop an appropriate approach to their advantage, which can yield sustainable improvement in service quality as perceived by patients and professionals. Hospitals can make better quality decisions based on structured measurement and knowledge. It is recommended that managers apply this knowledge for successful implementation of activities related to service quality in their organizations. 相似文献

Neospora caninum, an obligate intracellular protozoan parasite, is the causative agent of neosporosis, recognized as a major cause of bovine abortion around the world. Thailand is a developing agricultural country located in Southeast Asia. Livestock developments particularly in dairy cows of this country have been hampered by low productivity including milk and slow growth rate due to the impact of many pathogens including N. caninum. Currently, there is no effective method for control of neosporosis since there is less information regarding current status of infections. The objective of this study was to investigate the seroprevalence of neosporosis in dairy cows of the northern part of Thailand. During 2006–2007, the sera of 642 cows from 42 small farm holders with the top three highest consensus of dairy farms in the northern provinces, such as Chiang Rai, Chiang Mai and Lumpang were collected and performed tests. Antibodies to N. caninum were assayed by enzyme-linked immunosorbent assay (ELISA) with recombinant N. caninum surface antigen 1 (NcSAG1) and indirect fluorescent antibody test (IFAT). The overall prevalence of N. caninum infection in this study was 46.9% (301/642) by ELISA and 34.3% (220/642) by IFAT. 相似文献

The researchers conducted this grounded theory study in order to describe the decision making surrounding management of the pregnancy experience of 38 pregnant, HIV-infected Thai women. Data were collected using in-depth interviews and an open-ended questionnaire, and they were analyzed using constant comparative analysis. We found that “weighing distress” was the core category of the decision-making process. The supporting categories were being ambivalent about continuing the pregnancy, exploring alternative options, and selecting the appropriate choice. Health care providers should encourage family members to participate and be involved in the women's decision-making processes. 相似文献
