Objective: Abdominal weights was used to strengthen the diaphragm of a C6 ASIA (A) tetraplegic subject with the aim of studying the long term effect of the technique as a part of respiratory rehabilitation. Setting: Department of Physical Medicine and Rehabilitation, Christian Medical College, Vellore, Tamil Nadu, India. Study Design: Prospective case study. Material and methods: The peak EMG amplitude of the diaphragm (DIA), intercostals (INT) and sternoclidomastiod (SCM) were assessed using a surface EMG and inspired lung volume (ILV) was assessed using an adjustable portable spirometer. The measurements were repeated after 3, 6, 9 and 12 months of inspiratory muscle training for a period of 15 minutes daily, 6 days a week for 12 months. Results and discussion: Peak amplitudes recorded by the EMG of DIA and SCM muscles showed a progressive increase, INT muscle did not show a consistent change. INV showed a gradual rise from 1772ml to 2760 ml over the study period. These values have the following significance: 1) Use of abdominal weights as a part of respiratory rehabilitation has beneficial long term effects;2) In patients with tetraplegia, respiratory muscles in particular the diaphragm, are trainable in terms of muscle efficiency;3) The improvement in the muscle efficiency obtained during the early rehabilitation can be maintained or improved using simple non sophisticated exercises like abdominal weights post discharge. Conclusions: Abdominal weights can be used as an effective adjunct to pulmonary rehabilitation in improving the efficiency of diaphragm on a long term basis, thereby reducing the risks associated with pulmonary complications.

Introduction: Intracellular calcium concentration ([Ca2+]i) is a critical parameter in cellular homeostasis, including articular chondrocytes. Perturbed [Ca2+]i of chondrocytes may be associated with joint disease. The objective of the study was to compare large animal models for investigating Ca2+ homeostasis in chondrocytes. Materials and Methods: The gross anatomy of the metacarpophalangeal joint (MCP) of cattle and sheep was compared, along with the effect of various manoeuvres used to study the mechanisms of Ca2+ homeostasis in chondrocytes from load-bearing areas. The gross anatomy was observed before and after dissection, and internal architecture was examined after sectioning. Cartilage thickness was measured with a digital micrometer. Chondrocyte yield was determined after isolation. Chondrocytes were incubated with Fura-2 and Ca2+i followed in different extracellular conditions. A hypotonic shock (HTS) was used to mimic removal of a load. Results: The results showed that ovids and bovids were skeletally immature and aspects of Ca2+ homeostasis were similar. Ovine chondrocytes had higher resting fluorescence, consistent with elevated resting Ca2+ levels. Results from ion substitution experiments were consistent with a role for Na+/Ca2+ exchange, and swelling-induced Ca2+ enters into the cytoplasm via the plasma membrane and intracellular stores. Conclusions: Ca2+ homeostasis in chondrocytes from both species behaved in a similar manner to HTS and ion substitutions. Differences in resting [Ca2+]i could be associated with species, stage of maturation, or Fura-2 itself and require further investigation. These findings contribute to our understanding of the physiology of articular cartilage in different species, and their potential use as models for studying joint disease in humans.

Objective: To compare the effectiveness of ab-dominal weights and incentive spirometry for improving the strength of diaphragm in tetra-plegics. Setting: Department of Physical Medicine and Rehabilitation, Christian Medical College, Vel-lore, Tamil Nadu, India. Study Design: Two group comparison study Methods: Seventeen patients who fulfilled the inclusion criteria were assigned into an ABW or INS treatment groups using judgment sampling after obtaining an informed consent. Evaluation of the chest, respiratory status, vital signs and strength of diaphragm were done during initial assessment. ABW group underwent diaphrag-matic strengthening using Abdominal weights (ABW) and INT group with Incentive Spirometer (INS) for 15 minutes daily, 6 days a week, for a period of 6 weeks. The pre and post training values of peak amplitude in electro myogram (EMG) of the diaphragm, intercostals and ster-nocleidomastoid muscles were measured. Statistical analysis: The analysis was done using SPSS 11. The pre and post-training values of peak EMG amplitudes of the diaphragm, inter- costals and sternocleidomastoid were com- pared within the groups using Wilicoxon’s sign test and between the two groups using Mann- Whitney’s test. Results: The peak EMG of diaphragm of ABW group raised from 1.1289 to 1.3036 milli-volts with a significance of p<0.001, whereas it fell from 1.7001 to 1.0441 milli-volts among INS group subjects with a significance of p<0.001. Comparison between the 2 groups showed sta-tistically significant improvement in diaphrag-matic strength among the ABW group. Conclusion: The results of this study sug-gests that, in the pulmonary rehabilitation of motor complete tetraplegic subjects abdominal weighted training of the diaphragm has better results in improving the strength of the ***: Fluid research grant of Christian Medical College, Vellore.

Background: Lack of an observable vertical impact peak in fore/mid-foot running has been suggested as a means of reducing lower extremity impact forces, although it is unclear if impact characteristics exist in other axes. The purpose of the investigation was to compare three-dimensional(3 D) impact kinetics among foot-strike conditions in over-ground running using instantaneous loading rate–time ***: Impact characteristics were assessed by identifying peak loading rates in each direction(medial–lateral(ML), anterior–posterior(AP),vertical, and 3 D resultant) following foot-strike instructions(fore-foot, mid-foot, subtle heel, and obvious heel strike). Kinematic and kinetic data were analyzed among 9 male participants in each foot-strike ***: Loading rate peaks were observed in each direction and foot-strike condition, differing in magnitude by direction(3 D resultant and vertical > AP > ML, p ≤ 0.031) and foot-strike: ML(fore-foot and mid-foot strike > obvious heel strike, p ≤ 0.032), AP(fore-foot and mid-foot strikes > subtle-heel and obvious heel strikes, p ≤ 0.023). In each direction, the first loading rate peak occurred later during heel strike running relative to fore-foot(p ≤ 0.019), with vertical and 3 D resultant impact durations exceeding shear(ML and AP, p ≤ 0.007) in each ***: Loading rate–time assessment identified contrasting impact characteristics in each direction and the 3 D resultant following foot-strike manipulations, with potential implications for lower extremity structures in running.

AIM: To assess numbers and case fatality of patients with upper gastrointestinal bleeding(UGIB),effects of deprivation and whether weekend presentation affected ***: Data was obtained from Information Services Division(ISD) Scotland and National Records of Scotland(NRS) death records for a ten year period between 2000-2001 and 2009-2010. We obtained data from the ISD Scottish Morbidity Records(SMR01) database which holds data on inpatient and daycase hospital discharges from non-obstetric and nonpsychiatric hospitals in Scotland. The mortality data was obtained from NRS and linked with the ISD SMR01 database to obtain 30-d case fatality. We used 23 ICD-10(International Classification of diseases) codes which identify UGIB to interrogate database. We analysed these data for trends in number of hospital admissions with UGIB,30-d mortality over time and assessed effects of social deprivation. We compared weekend and weekday admissions for differences in 30-d mortality and length of hospital stay. We determined comorbidities for each admission to establish if comorbidities contributed to patient outcome. RESULTS: A total of 60643 Scottish residents were admitted with UGIH during January,2000 and October,2009. There was no significant change in annual number of admissions over time,but there was a statistically significant reduction in 30-d case fatality from 10.3% to 8.8%(P < 0.001) over these 10 years. Number of admissions with UGIB was higher for the patients from most deprived category(P < 0.05),although case fatality was higher for the patients from the least deprived category(P < 0.05). There was no statistically significant change in this trend between 2000/01-2009/10. Patients admitted with UGIB at weekends had higher 30-d case fatality compared with those admitted on weekdays(P < 0.001). Thirty day mortality remained significantly higher for patients admitted with UGIB at weekends after adjusting for comorbidities. Length of hospital stay was also h
