The methylation response as well as the level of methyl donor substance, 5-adenosyl-L-methionine (SAM) has been suggested to be related to hepatotoxicity including hepatocarcinogenesis. But direct correlation between protein methylation and hepatotoxicity has not been established to the present. To observe relationship between protein methylation and short-term hepatotoxicity induced by chemical substances, the activities of protein methylase I and II (PM I, PM II) were examined in cytosolic fraction of SD rat treated orally with acetaminophen(AA), $\alpha$-naphtyl-isothiocyanate (ANIT) and tetracycline (TC) that was known to produce necrosis, cholestasis and steatosis respectively. To evaluate the degree of hepatotoxicity induced by each chemicals, we observed the serum levels of indicative parameters and histopathological alteration. In AA treated group, the activities of PM I were increased at 6, 12 hours after administration, prior to the appearance of the hepatotoxicity by clinical parameters. It was suggested that the levels of PM I were related with the initial stage of hepatotoxic mechanism induced by AA. In ANIT treated group, though most of clinical parameters were significantly increased at 24, 48 hours after administration, the activity of PM I was not changed, indicating that ANIT induced hepatotoxicity was not coupled to protein methylation.

Background: Type 2 diabetic mellitus (T2DM) is an emerging global pandemic which is associated with lots of co-morbidities and reported vascular dysfunctions. T2DM associated vascular dysfunctions leads to vasculopathy in the form of altered peripheral vascular dynamics. Cold stress test (CST) is a reliable sympathetic reactivity test used for assessing vascular dysfunctions. In this study we are trying to quantify vascular dysfunctions in T2DM patients non invasively by various parameters of photoplethysmography (PPG) of cold stress test. Methods: Case control study had done in referral health center AIIMS, Raipur. Parameters are recorded by finger-PPG before, during and after CST (1 min) in 2 groups, control (n = 20 healthy volunteers) and case (n = 20 diagnosed T2DM patients). Results: Due to cold stress, PPG parameter peak amplitude was significantly decreased in both healthy and T2DM groups (p <0.001 and p <0.001, respectively). However, recovery trend of amplitude was significantly slow in T2DM compared to healthy subjects. Another PPG parameter peak to peak interval was significantly higher in healthy group compared to T2DM patients. Conclusions: This study showed that T2DM patients has significant deranged pulse volume parameters like amplitude and peak to peak interval can be used to objectively quantify the vasculopathy in T2DM patients by using sympathetic reactivity to cold stress.

Objective: The aim of this research was to investigate the current status and limitations of the clinical use of a pulse tonometry device (PTD). Methods: We searched online medical databases, including Oriental Medicine Advanced Searching Integrated System (OASIS), Research Information Sharing Service (RISS), DataBase Periodical Information Academic (DBpia) and PubMed, for clinical studies of metabolic diseases that used PTD. We selected articles on the clinical application of the PTD but excluded duplicate articles, clinical studies without the PTD, and non-clinical studies. In the first screening, 551 articles were selected. Ultimately, we found 10 articles and classified the articles according to the following diseases: hyperlipidemia, diabetes, overweight and obesity, hypertension, and metabolic disease. Results: Of the 10 selected articles, 4 were focused on hypertension. Two articles were focused on overweight or obesity and two articles were focused on the metabolic disease. Conclusions: This study was the first attempt to conduct a systematic review on clinical studies of metabolic disease using the PTD as a primary outcome. We suggest that the standard of pulse wave parameters and operating procedures for the PTD should be further developed. The results of this study are expected to be used as basic information for the planning and progression of clinical studies of metabolic syndrome using PTD.

Background: There is growing evidence that there are differences in histological and genetic characteristics along with clinical behavior between right- and left-sided colon carcinomas. We have compared various parameters of the two types and assessed associations of the results with prognosis in patients in Pakistan. Materials and Methods: We reviewed 200 cases from our institutional database; 100 cases of right-sided and 100 cases of left-sided colon cancer. Parameters including age, gender, TNM stage, histological features and clinical outcome were analyzed. Results: The patients with right-sided colon cancer were significantly older as compared to their counterparts with left-sided cancer. They presented with a lumbar mass rather than symptoms of obstruction and perforation as seen in left-sided colon cancers, and the histology showed higher percentage of poorly differentiated tumors with advanced pT stage. Moreover, Crohn's-like reactions, intra tumoral lymphocyte responses and other poor prognostic factors like lymph vascular invasion and perineural invasion were more common in right-sided cancers. Conclusions: We found that right- and left-sided colon cancers are different from each other in terms of clinical presentation, histology and clinical behavior. Right-sided colon cancers are more aggressive and are associated with poorer clinical outcome as compared to left sided colon cancers in our population.

Purpose: Host modulatory therapy has been proposed as a treatment for periodontal diseases. A class of herbal medicines, known to be immunomodulators, alters the activity of immune function through the regulation of informational molecules such as cytokines. In the current study, we tested the hypothesis that herbal immunomodulator drugs act as an adjuvant to scaling and root planing (SRP) in alleviating periodontal inflammation by improving clinical and biochemical parameters. Methods: Sixty healthy subjects (30 in each group) with moderate and severe chronic periodontitis were enrolled in a double-blind, placebo-controlled, double-masked randomised controlled trial. The control group was treated with SRP and a placebo, whereas the test group was treated with SRP followed by dietary supplementation of Septilin for 3 weeks. Periodontal clinical parameters and serum C-reactive protein (CRP) levels were evaluated for all patients at the baseline, 3 weeks, and 6 weeks. Results: Improved gingival index scores found in the test group as compared to the control group were found to be statistically significant only after 3 weeks (P<0.001). In contrast, the decrease in the sulcus bleeding index and pocket depth scores was statistically highly significant in the test group as compared to the control group after 3 weeks and 6 weeks (P<0.001). However, reduced clinical attachment level and CRP scores, as reflected in the test group as compared to the control group, were not found to be statistically significant after both 3 weeks (P>0.05) and 6 weeks (P>0.05). Conclusions: The results of this clinical-biochemical study suggest that dietary supplementation with herbal immunomodulatory agents may be a promising adjunct to SRP and may aid in improving periodontal treatment outcomes.

Objectives: To compare the clinical and radiological outcomes after closed reduction (CR) and open reduction and internal fixation (ORIF) in the management of subcondylar fractures. Materials and Methods: Forty-eight patients presenting with subcondylar fracture between January 2010 and March 2013 were evaluated retrospectively. Fifteen patients were treated with CR and 33 patients with ORIF. The clinical and radiologic parameters were evaluated during follow-up (mean, 7.06 months; range, 3 to 36 months). Results: In the CR group, no patients had any problems with regard to the clinical parameters. The average period of maxillomandibular fixation (MMF) was 5.47 days. The preoperative average tangential angulation of the fractured fragment was $3.67^{\circ}$, and loss of ramus height was 2.44 mm. In the ORIF group, no clinical problems were observed, and the average period of MMF was 6.33 days. The preoperative average tangential angulation of the subcondylar fragment was $8.66^{\circ}$, and loss of ramus height was 3.61 mm. Conclusion: CR provided satisfactory clinical results, though ORIF provided more accurate reduction of the fractured fragment. So there is no distinct displacement of fractured fragment, CR should be selected than ORIF because of no need for surgery.

Purpose: The aim of this study was to evaluate clinical and radiographic changes and the survival rate after periodontal surgery using deproteinized bovine bone mineral (DBBM) with 10% collagen or DBBM with a collagen membrane in endo-periodontal lesions. Methods: A total of 52 cases (41 patients) with at least 5 years of follow-up were included in this study. After scaling and root planing with or without endodontic treatment, periodontal regenerative procedures with DBBM with 10% collagen alone or DBBM with a collagen membrane were performed, yielding the DBBM + 10% collagen and DBBM + collagen membrane groups, respectively. Changes in clinical parameters including the plaque index, bleeding on probing, probing pocket depth, gingival recession, relative clinical attachment level, mobility, and radiographic bone gains were evaluated immediately before periodontal surgical procedures and at a 12-month follow-up. Results: At the 12-month follow-up after regenerative procedures, improvements in clinical parameters and radiographic bone gains were observed in both treatment groups. The DBBM + 10% collagen group showed greater probing pocket depth reduction ($4.52{\pm}1.06mm$) than the DBBM + collagen membrane group ($4.04{\pm}0.82mm$). However, there were no significant differences between the groups. Additionally, the radiographic bone gain in the DBBM + 10% collagen group ($5.15{\pm}1.54mm$) was comparable to that of the DBBM + collagen membrane group ($5.35{\pm}1.84mm$). The 5-year survival rate of the teeth with endo-periodontal lesions after periodontal regenerative procedures was 92.31%. Conclusions: This study showed that regenerative procedures using DBBM with 10% collagen alone improved the clinical attachment level and radiographic bone level in endo-periodontal lesions. Successful maintenance of the results after regenerative procedures in endo-periodontal lesions can be obtained by repeated oral hygiene education within strict supportive periodontal treatment.

Objectives: This study investigated the clinical characteristics of functional dyspepsia (FD) patients with food retention (FR) in regard to the parameters of cutaneous electrogastrography (EGG), Ryodoraku, and heart rate variability (HRV). Methods: This study reviewed the clinical records of 33 FD patients with FR who filled out the FR Questionnaire for FD (FRQ-FD) and underwent EGG for six months from March 1st, 2021. We summarized the clinical characteristics of FD patients with FR and analyzed the correlation between FRQ-FD score and parameters of EGG, Ryodoraku, and HRV. Results: FRQ-FD scores had a positive correlation with percentage of postprandial bradygastria and negative correlation with power ratio, detected on Channel 2, 3 of EGG. The total average (TA) Ryodoraku score was lower, and the high frequency density (HF) of HRV was higher than the normal value. Conclusions: The results of this study suggest that clinicians can use EGG, Ryodoraku, and HRV to increase the accuracy of diagnosing FR in FD patients.

Background : Sepsis is a clinical syndrome characterized by a systemic inflammatory and hemodynamic response to severe bacterial infections that involve various mediators. Endothelin (ET)-1, a potent vasoconstrictor is associated with mu1tiple organ failure, and interleukin (IL)-8, a proinflammtory cytokine, plays a major role in neurophil activation. Both have been reported to be useful parameters in the clinical assessment of sepsis. The levels of ET-1 and IL-8 in the blood were measured in patients with sepsis, and the correlation of both parameters and their relationship with the clinical data was assessed. Methods : 19 sepsis patients and 17 controls were studied. Blood samples of the sepsis patients were drawn in day 1, 3, 7, and 14. The APACHE III scores were calculated in concurrent days. The ET-1 and IL-8 levels were measured using immunoassay methods. Results : The ET-1 levels of patients with sepsis were significantly higher than in the controls. In patients with sepsis, non-survivors had higher ET-1 levels than survivors on day 1 and 7, and patients with shock also had higher ET-1 levels than normotensive patients on admission. The ET-1 levels were significantly correlated with the creatinine levels on day 1, 7, and 14. The IL-8 levels showed a significant correlation with the ET-1 levels on day 14. Conclusion : ET-1 was found to be closely related with the clinical outcome, shock, and renal failure, and showed a correlation with IL-8. These mediators can be considered not only to play pathophysiologic roles but also as useful parameters in the clinical assessment of sepsis.
