HemoHIM was used as a Korean traditional medicine for anti-inflammatory and antioxidant effects. However, there is no study on the effect of HemoHIM on fatigue. We examined the potential use of HemoHIM to determine whether it can induce anti-fatigue effects. Mice were administered with HemoHIM and VEH for 14 days. On the last day of treatment, mice were subjected to behavioral tests. Subsequently, their plasma and muscle were collected after the treadmill test to measure lactate, lactate dehydrogenase (LDH), ammonia, corticosterone, glycogen, and creatine kinase (CK). We found that HemoHIM moderately increased the running time (s) in the treadmill and mobility duration in the cold swimming tests. In addition, the VEH group showed a significant increase in lactate, LDH, and corticosterone levels in the plasma compared to the group that did not perform the test. However, this was moderately reduced in HemoHIM treatment. Moreover, the HemoHIM-treated group showed significant differences in LDH and glycogen levels, and showed significantly different CK levels in the muscle. HemoHIM is considered to be effective in improving fatigue, given the duration of cold swimming or running time on a treadmill. Also, HemoHIM treatment resulted in reduced concentrations of blood and muscle parameter analysis.

Purpose: Despite previous studies reporting the development of rhabdomyolysis (RM), this affliction tends to be neglected as an envenomation sign in South Korea. The current retrospective study investigates the prevalence and prognosis of RM after a snakebite. We further searched for predictors of snakebite-induced RM, which can be observed at presentation. Methods: This study included 231 patients who presented to the ED within 24 hours after a snakebite. The patients were classified according to the severity of RM, and the data, comprising baseline characteristics and clinical course including the level of creatine kinase (CK), were collected and compared according to the severity of RM. Results: The prevalence of RM and severe RM were determined to be 39% and 18.5%, respectively. Compared to the group without RM or with mild RM, the group with severe RM had a higher grade of local swelling, a higher frequency of acute kidney injury and neurotoxicity, and a greater need for renal replacement therapy and vasopressor administration. However, the incidence of acute renal injury in the RM group was 7.7%, with two patients needing renal replacement therapy. No mortalities were reported at discharge. Results of the multinomial logistic regression model revealed that the WBC levels are significantly associated with the risk of severe RM. Conclusion: RM should be considered the primary clinical sign of snake envenomation in South Korea, although it does not seem to worsen the clinical course. In particular, physicians should pay attention to patients who present with leukocytosis after a snakebite, which indicates the risk of developing RM, regardless of the CK level at presentation.
This study was designed to investigate the effect of vibratory stimulation on recovery of muscle function from delayed onset muscle soreness (DOMS). Volunteers performed 3 set of 70 % maximal voluntary eccentric muscle contraction and induced DOMS. volunteers were allocated to one of three treatment group after DOMS : group I (control), group II (ultrasound), group III (vibration). Maximal Voluntary Isometric Contraction (MVIC), Visual Analog Scale (VAS), Range Of Motion (ROM), Root Mean Square (RMS), Median frequency (MDF), Blood Serum Creatine Kinase (CK), Lactic dehydrogenase (LDH) were recorded at baseline, and 24, 48, 72 hours post-exercise. In MVIC measurement, there was a statistically significant difference in group III compared to group I (p < .05). In VAS measurements, there were a statistically significant difference in group II and III compared to group I (p < .05). In ROM measurement, there was a statistically difference in group II and III compared to group I (p < .05). In Muscle Volume with Ultrasonography measurement, there was no statistically significant difference in any groups (p > .05). In RMS and MDF measurement, there were a statistically significant difference in group II and III compared to group I (p < .05). In Blood samples of CK and LDH measurements, There were no statistically significant difference in any groups (p > .05). From the above result, Vibratory stimulation had a positive effect on recovery of muscle function from delayed onset muscle soreness. Further studies should be undertaken to ascertain the more effectiveness of vibratory stimulation and may be a promising treatment modality.
The antidepressant drug trazodone (TRZ) is commonly used for treating depression, anxiety, and insomnia, however, it causes cardiotoxicity, which is one of its limitations. The objective of this work was to investigate the impact of sage (Salvia officinalis) in rats against cardiotoxicity induced by TRZ and to investigate the mechanisms involved in its cardio-protective properties through autophagy and oxidative stress. Fifty male albino rats were split randomly into five experimental groups: control group, sage oil group (100 mg/kg), TRZ group (20 mg/kg), protective group, and curative group. Cardiac function biomarkers (aspartate aminotransferase [AST], creatine kinase-MB [CK-MB], and cardiac troponin T [cTnI]) were assessed in serum. Oxidative stress and inflammatory biomarkers in cardiac tissue (total antioxidant capacity, malondialdehyde, and tumor necrosis factor-α) were evaluated. Heart tissues were subjected to histological, immunohistochemical, and ultrastructural evaluations. DNA damage also evaluated. Significant rise in the levels of AST, CK-MB, and cTnI were observed with enhanced autophagy along with marked histopathological changes in the form of interrupted muscle fibers with wide interstitial spaces with areas of hemorrhage and extravasated blood and interstitial mononuclear cellular infiltration in TRZ group. DNA damage was also significantly increased in TRZ group. However, administration of sage in both protective and curative groups show marked improvement of the cardiac alterations. In conclusion, sage ameliorated the alterations in the heart induced by trazadone through modulation of autophagy and oxidative stress.

Background: Hypomagnesemia is a common complication after cardiac surgery with cardiopulmonary bypass. The purpose of this study was to assess the clinical beneficial effect of administration of magnesium sulfate in cardiac surgery. Material and Method: Thirty five patients scheduled for elective cardiac surgery were randomly assigned to magnesium group (n=20) which received magnesium sulfate in priming solution (1 g) and cardioplegic solution (1 g) or control group (n=15) which did not receive it. Arterial blood samples were drawn for measuring $Mg^{++}$ and electrolytes contents, blood gas analysis, CBC, total protein, albumin, blood urea nitrogen (BUN), creatinine, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, tumor necrosis factor-${\alpha}$$(TNF-{\alpha})$, interleukin-6 (IL-6), interleukin-10 (IL-10), creatine phosphokinase (CpK), creatine kinase-MB (CK-MB), lactate dehydrogenase(LDH), troponin-1 (TNI), prothrombin time (PT) and activated pratial thromboplastin time level (aPTT). Venous blood samples were drawn before and after the operation for measuring activated clotting time level (ACT). Result: $Mg^{++}$ levels in magensium group were higher than those of control group at intraoperative and post-operative periods (p<0.05). dysrhythmias were lower in magnesium group (8 cases out of 17 patients, 46.4%) than in control group (10 cases out of 10, 100%, p=0.050). Conclusion: These results showed that administration of low dose magnesium sulfate during cardiac surgery prevented hypomagnesemia and lowered incidence of dysrhythmia.
Among semi-quantitative or fully quantitative lateral flow assay readers, an image sensor-based instrument has been widely used because of its simple setup, cheap sensor price, and compact equipment size. For all previous approaches, monochrome CCD or CMOS cameras were used for lateral flow assay imaging in which the overall intensities of all colors were taken into consideration to estimate the analyte content, although the analyte related color information is only limited to a narrow wavelength range. In the present work, we introduced a color CCD camera as a sensor and a color decomposition method to improve the sensitivity of the quantitative biosensor system which utilizes the lateral flow assay successfully. The proposed setup and image processing method were applied to achieve the quantification of imitatively dispensed particles on the surface of a porous membrane first, and the measurement result was then compared with that using a monochrome CCD. The compensation method was proposed in different illumination conditions. Eventually, the color decomposition method was introduced to the commercially available lateral flow immunochromatographic assay for the diagnosis of myocardial infarction. The measurement sensitivity utilizing the color image sensor is significantly improved since the slopes of the linear curve fit are enhanced from 0.0026 to 0.0040 and from 0.0802 to 0.1141 for myoglobin and creatine kinase (CK)-MB detection, respectively.
We investigated the effects of aprotinin, a protease inhibitor, on isolated rat heart subjected to cardioplegia and global ischemia for 4 hours and then reperfused for 40 minutes. Before ischemia, hearts were perfused with either aprotinin 1x105KIU/L[Aprotinin group,n=8 or no aprotinin[control group,n=8 added to Krebs-Henseleite solution for 30 minutes. Hemodynamic and biochemical parameters such as heart rate, LVP, dP/dt, coronary flow and creatine kinase were measured before cardioplegia and after reperfusion 10,20,30,40 minutes. After completion of experiment, wet and dry heart weight were measured for tissue water and water content evaluation. On reperfusion, recovery of LVP of aprotinin group at each time point was significantly better than that of control group[p<0.05 , and of dP/dt at reperfusion 40 minutes[p=0.034 . No statistically significant differences in heart rate, coronary flow and CK were observed between the two groups, but aprotinin group seemed to have better recovery. No significant differences in tissue water and water content were observed between the two group.These results suggest that pretreatment of aprotinin is effective in myocardial preservation in prolonged hypothermic ischemia and reperfusion.
Fructose-l, 6-diphosphate as an additive to cold crystalloid cardioplegia [St. Thomas sol.] was studied prospectively in 60 patients undergoing open heart surgery from January 1, 1991, to June 30, 1991. Thirty patients received cardioplegia with FDP[group I ] and 30 patients received cardioplegia without FDP [group II ]. There were no differences between two groups pre-operatively with regard to age, heart disease, cross-clamp time, cardiac enzymes, or hemodynamic measurements [p>0.05]. Cardiopulmonary bypass was established using ascending aorta and vena cava cannulation employing moderate systemic hypothermia [30oC nasopharyngeal temperature] and hemodilution All patients received cardioplegia through the aortic root at aortic root pressure of 80mm Hg. The composition of the cardioplegic solution and its delivery were identical in both groups except for the addition of FDP[1.5 mg/mL] in group I. The cardioplegic infusate consisted of St. Thomas Hospital solution. The initial dose was infused through the aortic root. Topical myocardial cooling with saline slush was employed in all patients. Recorded operative data were cardiopulmonary bypass and cross-clamp times, amount of cardioplegic infusate. Blood samples for assessment of lactate dehydrogenase [LDH], creatine kinase [CK] and transaminases [GOT, GPT] were obtained before and at 1,2,3,7th postoperative period. Better myocardial protection effect was noted in group I than group II with respect to the % change of cardiac enzymes, although the differences were not significant. We conclude that FDP is a safe additive to crystalloid cardioplegia and may be beneficial in open heart surgery patients.

The purpose of this study was to identify the effect of resistance training intensity levels on muscle damaged index and aging-related hormones in obese middle-aged women. Thirty middle-aged women having over 30% of body fat participated in this study. The subjects were assigned into 3 groups on the basis of workout intensity, 50% intensity, 60% intensity, and 70% intensity. After performing three different types of exercise for 12 weeks, the levels of creatine kinase (CK), lactate dehydrogenase (LDH), melatonin, dehydroepiandrosterone-sulphate (DHEA-S), and growth hormone (GH) in all subjects were assessed before and after the program. Muscle damaged index was effectively changed in low exercise intensity group. However, aging-related hormones were effectively changed in high exercise intensity group. DHEA-S and GH were significantly increased in the 70% intensity group than the other groups.
Although canine facial nerve paralysis(FNP) occurs similarly in humans, there is no properly recognized therapy using Western medicine for idiopathic causes. To elucidate therapeutic measures by acupuncture(AP) on canine FNP, we examined the therapeutic effect of injection-AP on the artificially induced canine FNP. Twelve dogs on artificially induced canine FNP were divided into a control group(4 dogs), an experimental dexamethasone-treated group(dexamethasone group, 4 dogs) and an experimental bee venom-treated group(apitoxin group, 4 dogs). Saline (1 ml) was intramuscularly injected into the head muscle after the induction of FNP in the control group. On the other hand, injection-AP with dexamethasone was performed on such acupoints as LI04, LI20, ST02, ST07, TH17, SI18, GB03 and GB34, twice per week after induction of FNP in the dexamethasone group. In addition, injection-AP with $100{\mu}g$ of apitoxin was performed on the same acupoints as the dexamethasone group twice per week after the induction of FNP in the apitoxin group, respectively. The changes of the clinical symptoms of FNP with each treatment during the experimental period were recorded by using clinical scores, respectively. The changes of serum creatine kinase(CK) activities along with each treatment were determined using an autoanalyzer. The significant differences of clinical scores were detected on day 14(p<0.05) in the apitoxin and dexamethasone groups, compared with those in the control group, respectively. However, significant difference was not detected between the apitoxin and dexamethasone groups. Significant differences of serum CK activities were detected on day 7(p<0.05) and day 14(p<0.05) in the dexamethasone and apitoxin groups, compared with those in the control group, respectively. However, significant difference was not detected between the dexamethasone and apitoxin groups. In condition, injection-APs with apitoxin and dexamethasone were all effective for treatment of canine FNP and the therapeutic effect by injection-AP with apitoxin was similar to that of injection-AP with dexamethasone.
