Twenty patients with nodulocystic acne were randomly allocated to one of two treatment schedules: 1) Tetracycline 500 mg or 2) Tab. Gugulipid (equivalent to 25 mg guggulsterone). Both were taken twice daily for 3 months, and both produced a progressive reduction in the lesions in the majority of patients. With tetracycline, the percentage reduction in the inflammatory lesions was 65.2% as compared to 68% with gugulipid; on comparison, this difference was statistically insignificant (P>0.05). Follow-up at 3 months showed a relapse in 4 cases on tetracyline and 2 cases on gugulipid. An interesting observation was that the patients with oily faces responded remarkably better to gugulipid. 相似文献

Glial cells actively participate in synaptic transmission. They clear molecules from the synaptic cleft, receive signals from neurons and, in turn, release molecules that can modulate signaling between neuronal elements. Whether glial-derived transmitters can contribute to enduring changes in postsynaptic efficacy, however, remains to be established. In rat hypothalamic paraventricular nucleus, we demonstrate an increase in the amplitude of miniature excitatory postsynaptic currents in response to norepinephrine that requires the release of ATP from glial cells. The increase in quantal efficacy, which likely results from an insertion of AMPA receptors, is secondary to the activation of P2X(7) receptors, an increase in postsynaptic calcium and the activation of phosphatidylinositol 3-kinase. The gliotransmitter ATP, therefore, contributes directly to the regulation of postsynaptic efficacy at glutamatergic synapses in the CNS. 相似文献

Recent reports on gamete intra-Fallopian transfer (GIFT) inhospitals without IVF support have been encouraging. We reporton the use of GIFT and intrauterine insemination (IUI) at NorthamptonGeneral Hospital, where capital costs for setting up the programmehave been low. To date seven IUI and three GIFT treatments havebeen completed, resulting in three IUI positive pregnancy tests.One miscarried after several positive -HCGs and one GIFT pregnancywas achieved. 相似文献

Training in oral and maxillofacial surgery (OMFS) in the UK has undergone considerable changes during the last 10 years, and “core” surgical training has replaced “basic” surgical training. In 2014 a pilot “run-through” training programme from specialist training year one (ST1)-ST7 was introduced to facilitate early entry into the speciality. Run-through training guarantees that a trainee, after a single competitive selection process and satisfactory progress, will be given training that covers the entire curriculum of the speciality, whereas uncoupled training requires a second stage of competitive recruitment after the first one (for OMFS only) or two years of “core” training to progress to higher specialty training.The first two years of run-through training (ST1-ST2) are the same as for core surgical training. Dual-qualified maxillofacial aspirants and those in their second degree course are curious to know whether they should go for the uncoupled core surgical training or the run-through programme in OMFS. The General Medical Council (GMC) has now agreed that run-through training can be rolled out nationally in OMFS. To assess the two pathways we used an online questionnaire to gain feedback about the experience from all OMFS ST3 and run-through trainees (ST3/ST4) in 2016–2017. We identified and contacted 21 trainees, and 17 responded, including seven run-through trainees. Eleven, including five of the run-through trainees, recommended the run-through training programme in OMFS. Six of the seven run-through trainees had studied dentistry first. The overall mean quality of training was rated as 5.5 on a scale 0–10 by the 17 respondents. This survey gives valuable feedback from the current higher surgical trainees in OMFS, which will be useful to the GMC, Health Education England, OMFS Specialist Advisory Committee, and those seeking to enter higher surgical training in OMFS. 相似文献

There is a relationship between arterial blood pressure, cardiac output and vascular resistance which can be described mathematically, and helps us to understand the short-term control of blood pressure in the terms of a hydraulic system. The sensors in this system are the arterial baroreceptors which mediate changes in the hydraulic system though control of the autonomic nervous system, which in turn influences heart rate, inotropy and vascular tone. Altering the distribution of blood between the arterial and venous systems compensates for acute changes in total blood volume. The total blood volume is controlled predominantly by the kidney, with the renin–angiotensin–aldosterone system acting as both the ‘sensor’ of blood pressure/volume (via renin release in the juxtaglomerular apparatus) and the ‘effector’ of blood pressure/volume (via aldosterone secretion by the adrenal cortex). Overall control is shared; the baroreceptors being responsible for mediating short-term changes, and renal mechanisms determining the long-term control of blood pressure. These systems have to be adaptable in order to deal with physiological variation in the delivery of blood to tissues from rest to exercise, and with the large shifts in blood volume seen in acute haemorrhage. Pathophysiological changes in these systems lead to maladaptive responses, with systemic hypertension the most commonly seen. 相似文献

The Internet is a powerful method of acquiring and sharing information. In marketing and business, online visibility is vital for publicity and the reputation of an organisation. To our knowledge, the importance of such visibility in medicine in general, and in Oral and Maxillofacial Surgery (OMFS) services in the UK, has not previously been investigated. We aimed to provide a better understanding of the way that patients use the Internet by asking 450 patients to complete a questionnaire when they attended outpatient OMFS departments at 2 centres. We also assessed the online visibility of the British Association of Oral and Maxillofacial Surgeons (BAOMS) and investigated the correlation between the strength of online visibility and professional reputation. Results from the self-administered, anonymous, validated questionnaires showed that 82% of patients agreed that the Internet was a powerful source of information, and two-thirds associated online visibility with a good reputation. However, the perceived online visibility of the BAOMS was poor (2%). This study mirrors findings in business publications, and confirms the link between online visibility and professional reputation. It also shows that there is a gap between patients’ perceptions and the level of uptake of professional resources. We propose various strategies to bridge this gap and to promote the online visibility and professional reputation of the BAOMS and of OMFS services in the UK. 相似文献
