Effect of a Caregiver's Education Program on Stroke Rehabilitation

OBJECTIVE: To evaluate effects of caregiver's education program on their satisfaction, as well as patient functional recovery, performed in addition to daily conventional rehabilitation treatment. METHODS: Three hundred eleven subjects diagnosed with first-onset stroke and transferred to the Department of Physical Medicine and Rehabilitation of Inha University Hospital were surveyed. In 2015, caregivers attended an education program for acute and subacute stroke patients. Patients who received an additional rehabilitation therapy were assigned to the experimental group (n=81), whereas the control group (n=100) consisted of transfer cases in 2014 with only conventional treatment. The experimental group was classified by severity using the Korean version of the National Institutes of Health Stroke Scale (K-NIHSS), which was administered to all 181 subjects, in addition to, the Korean version of the Mini Mental Status Examination (K-MMSE), a Modified Barthel Index (K-MBI), and the Berg Balance Scale (K-BBS). Caregiver satisfaction and burden before and after education programs were assessed using the Canadian Occupational Performance Measure (COPM), as well as family burden and caregiver burnout scales. RESULTS: No significant intergroup difference was observed between initial K-NIHSS, K-MMSE, K-BBS, K-MBI scores, and times from admission to transfer. Those with moderate or severe strokes under the experimental condition showed a more significant improvement than the control group as determined by the K-NIHSS and K-BBS, as well as tendential K-MMSE and K-MBI score increases. Satisfaction was significantly greater for family members and formal caregivers of patients with strokes of moderate severity in the experimental group. CONCLUSION: The caregiver's education program for stroke subjects had a positive outcome on patients' functional improvement and caregiver satisfaction. The authors believe that the additional rehabilitation therapy with the education program aids patients to achieve functional improvements for an optimal return to social life.

Transgenic expression of Korean type hepatitis C virus core protein and related mutants in mice

Hepatitis C virus (HCV) is a major causative agent in liver disease. In order to investigate if Korean type HCV core protein and its related mutants, S99Q and S116I, are cytopathic to liver, three types of transgenic mice were established. The expression of transgenes was confirmed by HCV specific RT-PCR and Western immunoblotting. The livers of all wild type core and S116I transgenic lineages remained largely histologically normal. However, the livers of the S99Q transgenic mice showed significant high level of cell dysplasia associated with the transgene expression in hepatocytes largely located around the central veins by in situ hybridization analysis. In conclusion, the mutant HCV core protein at S99Q may contribute to the progress of HCV induced liver disease.

Studies on the Effects of Biomedicinal Agents on Serum Concentration of Ca2+, P and ALP Activity in Osteoporosis-Induced Rats

The present study was carried out to investigate the effects of biomedicinal agents on Ca2+, P and alkaline phosphatase (ALP) levels in ovariectomized rats. Rats were ovariectomized bilaterally and were fed up with Ca2+ and P-free diet during 8(9,10) weeks to induce osteoporosis. Osteoporosis was determined by the extent of bone density and by lowering the concentrations of serum Ca2+, P and ALP activity every week. Rats in antler, safflower, ipriflavon, or coadminisrated with estrogen groups were administrated with feed supplement for 5 weeks to elucidate the protective and therapeutic effects against osteoporosis. The bone tissue was examined with electron microscope to determine the effects of each treatment on osteoporosis. 1. The levels of serum Ca2+ and P in osteoporosisinduced rats, administrated with antler, ipriflavon and estrogen groups, were little higher than those of control rats. However, the levels of serum Ca and P in ovariectomized rats were significantly higher than those of control group (p<0.05). 2. The activities of serum ALP in osteoporosisinduced rats, administrated with antler extract, safflower, ipriflavon, or co-admistrated with estrogen, were little increased in comparing with those of control group, but were significantly decreased in with combination of estrogen for 5 weeks. However, The connections were interrupted and the bone matrix was destroyed in the osteoporosis-induced rats. 3. The inter-trabecular connections were examined under electron microscope. The connections were well maintained and bone loss was without in the administration with antler, safflower, and ipriflavon with combination of estrogen for 5 weeks. However, The connections were interrupted and the bone matrix was destroyed in the osteoporosis-induced rats.

SR144528 as Inverse Agonist of CB2 Cannabinoid Receptor

It is now well established that several G protein- coupled receptors can signal without agonist stimulation (constitutive receptors). Inverse agonists have been shown to inhibit the activity of such constitutive G protein-coupled receptor signaling. Agonist activation of the Gi/o-coupled peripheral cannabinoid receptor CB2 normally inhibits adenylyl cyclase type V and stimulates adenylyl cyclase type II. Using transfected COS cells, we show here that application of SR144528, an inverse agonist of CB2, leads to a reverse action (stimulation of adenylyl cyclase V and inhibition of adenylyl cyclase II). This inverse agonism of SR144528 is dependent on the temperature, as well as on the concentration of the cDNA of CB2 transfected. Pertussis toxin blocked the regulation of adenylyl cyclase activity by SR 144528.
