Abstract
Background
Delayed door-to-balloon (DTB) time and deterioration of in-hospital mortality during the coronavirus disease 2019 (COVID-19) pandemic have been reported. Little is known about the impact of changes in in-hospital medical management before primary percutaneous coronary intervention (PCI) for COVID-19 such as screening test (antigen or polymerase chain reaction (PCR) tests, chest CT for excluding the pneumoniae) and primary PCI under full personal protective equipment (PPE) on DTB time and in-hospital mortality.
Purpose
The purpose of this study was to evaluate the impact of in-hospital medical management for COVID-19 on DTB time and in-hospital mortality during COVID-19 pandemic period.
Methods
We compared DTB time and in-hospital mortality of 502 ST-elevation myocardial infarction (STEMI) patients during COVID-19 pandemic (February 2020 and January 2021) with 2035 STEMI patients before pandemic (February 2016 and January 2020) using date from Mie ACS registry, a retrospective and multicenter registry.
Results
The COVID-19 screening tests before primary PCI and/or primary PCI under full PPE was performed on 173/502 (34.5%) patients (antigen or PCR tests; 39 (7.8%), chest CT; 156 (31.3%), full PPE; 11 (2.2%)). These patients had lower rate of achievement of DTB time ≤90 min compared with others (Figure 1A). Moreover, In-hospital management of COVID-19 screening tests and/or primary PCI under full PPE was an independent factor of DTB time>90 min with odds ratio of 1.94 (95% confidential interval: 1.37–2.76, p<0.001). In addition, in-hospital mortality of those patients was higher compared with others (Figure 1B).
Conclusion
In-hospital medical management for COVID-19 screening tests before primary PCI and/or primary PCI under full PPE was the independent factor of DTB time>90 min. This study reinforces the need to focus efforts on shortening DTB time, while controlling the epidemic of infection.

Abstract
Abstract
Background
Intra-Aortic Balloon Pumping (IABP) was widespread used in cases of Acute Coronary Syndrome (ACS) at daily clinical situation in Japan, even though the efficacy of IABP in AMI patients with cardiogenic shock was not proved. The aim of this study was to investigate the efficacy of IABP use in ACS patients in Japan.
Methods
We investigated 2-year all-cause-mortality of 2,660 enrolled ACS patients including 358 patients with IABP and 2,302 patients without IABP from Mie ACS registry.
Results
We compared a 1:1 propensity score-matched cohort of 426 ACS patients with or without IABP (n=213, respectively). 2-year mortality was significantly higher in patients with IABP than without IABP (p=0.02, Figure A). In addition, IABP usage was independent predictor of mortality with hazard ratio of 1.6 by multivariate analysis. However, 2-year mortality was not statistically different between 2 groups only when analyzed patients with shock (p=0.60, Figure B).
Figure 1
Conclusion
IABP was not commonly recommended in ACS patients. However, IABP was might as well used in some situation especially in shock.

Abstract
Background
Cardiovascular deaths are more frequently in hemodialysis (HD) patients compared to general population. However, difference of prognosis of acute coronary syndrome (ACS) patients with or without HD were not well evaluated.
Purpose
The purpose of this study was to evaluate the clinical and prognostic characteristics of ACS patients with HD compared to that of ACS patients without HD.
Methods
We investigated 3427 ACS patients including 63 HD and 3364 non-HD patients between 2013 and 2017 using date from Mie ACS registry, a retrospective and multicenter registry. The primary outcome was defined as all-cause mortality.
Results
HD patients showed significantly higher prevalence of diabetes mellitus, past treatment of coronary artery disease, history of myocardial infarction and Killip ≥2 compared to non-HD patients (p<0.05, respectively). During the follow-up periods (median 719 days), 425 (12.4%) patients experienced all-cause death. HD patients demonstrated the higher all-cause mortality rate compared to that of non-HD patients during the follow-up (11.9% versus 38.1%, p<0.001, chi square). Kaplan Meier survival curves demonstrated that HD and non-HD patients with Killip 1 showed similar 30-day mortality, and Killip ≥2 patients also showed similar prognosis (Left side of figure). On the other hand, all cause mortality at 2 years were higher in Killip 1 HD patients compared to Killip 1 non-HD patients and similar between Killip 1 HD patients and Killip ≥2 non-HD patients in the 30 days landmark analysis (Right side of figure). In addition, cox regression analyses for all cause mortality demonstrated that HD was a strongest independent prognostic factor not of 30-day mortality but of after 30-day mortality with hazard ratio of 4.09 (95% confidential interval: 2.32–7.21, p<0.001).
Figure 1
Conclusion
Careful management are required in chronic phase for ACS patients with HD even in Killip 1 classification.

Abstract
BACKGROUND/AIMS Gastroesophageal reflux disease (GERD)-related disorders of systemic sclerosis (SSc) patients have not been adequately investigated. METHODS Sixty-six SSc patients (5 males and 61 females; 56.6 ± 14.6 years old) who underwent esophagogastroduodenoscopy were analyzed on the basis of 16 background factors. They were additionally compared with 116 matched non-SSc subjects controlling age, sex, and use of proton pump inhibitors (PPIs). RESULTS The mean disease duration of 66 patients was 5.1 ± 8.1 years, and their breakdown was as follows: 53 (80.3%) with GERD, 38 (57.6%) with GERD-related symptoms, and 20 (30.3%) with reflux esophagitis (RE; LA-A: 10, LA-B: 5, LA-C: 4, LA-D: 1). Use of PPI (p = 0.0455), complication of interstitial lung disease (p = 0.0242), and history of cyclophosphamide therapy (p = 0.0184) denoted significant association with GERD-related symptoms. Older age (p = 0.0211) was significantly associated with RE. None of GERD-related disorders showed any difference between 37 diffuse cutaneous SSc and 29 limited cutaneous SSc patients. The matched analysis indicated that SSc patients had higher prevalence of GERD (p < 0.0001), GERD-related symptoms (p = 0.0034), and RE (p = 0.0002). CONCLUSION SSc patients tend to have worse GERD symptoms and severer RE. However, most SSc-associated factors did not show significant association with GERD-related disorders, indicating the difficulty in predicting GERD-related disorders among SSc patients.

Abstract
BACKGROUND Despite the marked increase of diverticulosis, its risk factors have not been adequately elucidated. We therefore aim to identify significantly associated factors with diverticulosis. We also aim to investigate the present state of diverticulosis in Japan. METHODS We reviewed the medical records from 1990 to 2010 that included the data of consecutive 62,503 asymptomatic colonoscopy examinees from the general population in Japan. Most recent 3,327 examinees were analyzed with 16 background factors. RESULTS Among the 62,503 subjects (47,325 men and 15,178 women; 52.1 ± 9.2 years old), diverticulosis was detected in 11,771 subjects (18.8%; 10,023 men and 1,748 women). The incidences of diverticulosis in 1990-2000 and 2001-2010 were respectively 13.0% (3,771 of 29,071) and 23.9% (8,000 of 33,432): the latter was much higher than the former in all age groups and for both genders. Considering the anatomical locations of colorectal diverticula, left-sided ones have markedly increased with age but not significantly changed with times. Univariate analyses of the 3,327 subjects showed significant association of diverticulosis with four basic factors (age, sex, body mass index, blood pressure), three life style-related factor (smoking, drinking, severe weight increase in adulthood), and two blood test values (triglyceride, HbA1c). The multiple logistic analysis calculating standardized coefficients (β) and odds ratio (OR) demonstrated that age (β = 0.217-0.674, OR = 1.24-1.96), male gender (β = 0.185, OR = 1.20), smoking (β = 0.142-0.200, OR = 1.15-1.22), severe weight increase in adulthood (β = 0.153, OR = 1.17), HbA1c (β = 0.136, OR = 1.15), drinking (β = 0.109, OR = 1.11), and serum triglyceride (β = 0.098, OR = 1.10) showed significantly positive association with diverticulosis whereas body mass index and blood pressure did not. CONCLUSIONS The large-scale data of asymptomatic colonoscopy examinees from the general population from 1990 to 2010 indicated that the prevalence of diverticulosis is still increasing in Japan. Age, male gender, smoking, severe weight increase in adulthood, serum HbA1c, drinking, and serum triglyceride showed significant positive association with diverticulosis.

Abstract
Background Double-contrast upper gastrointestinal barium X-ray radiography (UGI-XR) is one of the most widely conducted gastric cancer screening methods. It has been executed to find gastric cancer, but has not been usually executed to detect premalignant atrophic mucosa of stomach. To understand the meaning of UGI-XR-based atrophic gastritis, we analyzed its association with several causative factors including Helicobacter pylori (HP) infection. Methods We evaluated 6,901 healthy adults in Japan. UGI-XR-based atrophic gastritis was diagnosed based on the irregular shape of areae gastricae and its expansion in the stomach. Results Of the 6,433 subjects with no history of HP eradication and free from gastric acid suppressants, 1,936 were diagnosed as UGI-XR-based atrophic gastritis (mild: 234, moderate: 822, severe: 880). These were univariately associated with serum HP IgG and serum pepsinogen I/II ratio with statistical significance. The multiple logistic analysis calculating standardized coefficients (β) and odds ratio (OR) demonstrated that serum HP IgG (β = 1.499, OR = 4.48), current smoking (β = 0.526, OR = 1.69), age (β = 0.401, OR = 1.49), low serum pepsinogen I/II ratio (β = 0.339, OR = 1.40), and male gender (β = 0.306, OR = 1.36) showed significant positive association with UGI-XR-based atrophic gastritis whereas drinking and body mass index did not. Among the age/sex/smoking/drinking-matched 227 pairs derived from chronically HP-infected and successfully HP-eradicated subjects, UGI-XR-based atrophic gastritis was detected in 99.1% of the former but in only 59.5% of the latter subjects (p<0.0001). Contrastively, UGI-XR-based atrophic gastritis was detected in 13 of 14 HP-positive proton pump inhibitor users (92.9%) and 33 of 34 HP-positive histamine H2-receptor antagonist users (97.1%), which are not significantly different from gastric acid suppressant-free subjects. Conclusions The presence of UGI-XR-based atrophic gastritis is positively associated with Helicobacter pylori infection, current smoking, age, decreased serum pepsinogen I/II ratio, and male gender. Eradication of Helicobacter pylori seems to superficially improve UGI-XR-based atrophic gastritis whereas intake of gastric acid suppressants does not.

Abstract
Background There have been very few reports assessing the relationship between various upper gastrointestinal (GI) symptoms or evaluating each individual upper GI symptom separately. Methods Based on the answers to Frequency Scale for the Symptoms of GERD from a large-scale population of healthy adults in Japan, a hierarchical cluster analysis was performed to categorize the typical 12 upper GI symptoms. The associations between the 12 symptoms and 13 background factors were systematically analyzed among the 18,097 digestive drug-free subjects, 364 proton-pump inhibitor (PPI) users, and 528 histamine H2-receptor antagonist (H2RA) users. Results The derived relationship between the 12 upper GI symptoms suggests the five symptom categories: heartburn (2), dyspepsia (4), acid regurgitation (3), pharyngo-upper esophageal discomfort (2), and fullness while eating (1). Among the digestive drug-free subjects, inadequate sleep, weight gain in adulthood, NSAID use, meals immediately prior to sleep, and frequent skipping of breakfast showed significant positive association with most upper GI symptoms. Compared to the digestive drug-free subjects, significantly associated factors for PPI and H2RA users are respectively different in “4 of 5” and “5 of 5” symptoms in heartburn and acid regurgitation categories, “1 of 2” and “1 of 2” symptoms in pharyngo-upper esophageal discomfort category, and “0 of 5” and “3 of 5” symptoms in dyspepsia and fullness while eating categories. These differences between digestive drug-free subjects and gastric acid suppressant users seem to correlate with our experiences in clinical situations: heartburn and acid regurgitation category symptoms are effectively controlled with PPI and H2RA whereas other category symptoms are not. Conclusions The 12 upper GI symptoms can be classified into five categories, which are statistically associated with various background factors. The differences of associated factors between digestive drug-free subjects and digestive drug users may be useful in studying the drug effects upon diverse upper GI symptoms.

Abstract
Background Despite the high prevalence of gastroesophageal reflux disease (GERD), its risk factors are still a subject of controversy. This is probably due to inadequate distinction between reflux esophagitis (RE) and non-erosive reflux disease (NERD), and is also due to inadequate evaluation of adjacent stomach. Our aim is therefore to define background factors of RE and NERD independently, based on the evaluation of Helicobacter pylori infection and gastric atrophy. Methods We analyzed 10,837 healthy Japanese subjects (6,332 men and 4,505 women, aged 20–87 years) who underwent upper gastrointestinal endoscopy. RE was diagnosed as the presence of mucosal break, and NERD was diagnosed as the presence of heartburn and/or acid regurgitation in RE-free subjects. Using GERD-free subjects as control, background factors for RE and NERD were separately analyzed using logistic regression to evaluate standardized coefficients (SC), odds ratio (OR), and p-value. Results Of the 10,837 study subjects, we diagnosed 733 (6.8%) as RE and 1,722 (15.9%) as NERD. For RE, male gender (SC = 0.557, OR = 1.75), HP non-infection (SC = 0.552, OR = 1.74), higher pepsinogen I/II ratio (SC = 0.496, OR = 1.64), higher BMI (SC = 0.464, OR = 1.60), alcohol drinking (SC = 0.161, OR = 1.17), older age (SC = 0.148, OR = 1.16), and smoking (SC = 0.129, OR = 1.14) are positively correlated factors. For NERD, HP infection (SC = 0.106, OR = 1.11), female gender (SC = 0.099, OR = 1.10), younger age (SC = 0.099, OR = 1.10), higher pepsinogen I/II ratio (SC = 0.099, OR = 1.10), smoking (SC = 0.080, OR = 1.08), higher BMI (SC = 0.078, OR = 1.08), and alcohol drinking (SC = 0.076, OR = 1.08) are positively correlated factors. Prevalence of RE in subjects with chronic HP infection and successful HP eradication denotes significant difference (2.3% and 8.8%; p<0.0001), whereas that of NERD shows no difference (18.2% and 20.8%; p = 0.064). Conclusions Significantly associated factors of NERD are considerably different from those of RE, indicating that these two disorders are pathophysiologically distinct. Eradication of Helicobacter pylori may have disadvantageous effects on RE but not on NERD.

Abstract
In this paper we present monitoring data of stream waters that may reflect acidic impacts on the island as well as the rainwater qualities. The pH ranges of the river water in the Kawara streams in the western part of the island and the Yodogo stream in the central part of the island were 5.71-6.35 and 5.85-6.12 during 1992-1999, respectively. The concentrations of SO4(2-) and NO3- in the river water were lower than those in the rainwater. Many differences were observed among the sampling sites. Higher concentrations of acid substances are found in the stream waters of the western area compared to the other areas. On the other hand, sulfuric acid is the major acid in the rainwater, snow and rime ice. No differences were observed in the ion constituents of the rainwater collected in the areas. These results suggested that the densely growing canopy may play a role in holding air pollutants, and acidic substances deposited on the canopy would be discharged as a through-fall and a stem flow. Furthermore, the water mass containing high ionic substances in the western area has been held in the groundwater layer, continuously supplying the stream waters during dry weather days. On the other hand, part of the basic runoff will be diluted with a surface runoff during the rainy days. As a result, the concentrations of the ionic substances in the stream waters during rainy days decreased.

Abstract
BACKGROUND & AIMS Alterations of hepatic cholesterol metabolism in patients with cholesterol gallstones are still controversial. This study investigated whether hepatic cholesterol metabolism is altered in Japanese patients with cholesterol gallstones. METHODS In this systematic study of 24 middle-aged nonobese and nondiabetic Japanese patients who had cholesterol gallstones and were undergoing elective cholecystectomy, an analysis of three regulatory enzymes in the cholesterol metabolism, as well as cytosolic total and free cholesterol levels and sterol carrier protein 2/nonspecific lipid transfer protein (SCP2/nsLTP) levels, was conducted using liver biopsy samples obtained during surgery. RESULTS The activities of 3-hydroxy-3-methyl-glutaryl-coenzyme A (HMG-CoA) reductase, cholesterol 7 alpha-hydroxylase, and acyl-CoA/cholesterol acyltransferase were not significantly different between patients and controls. Nevertheless, patients with gallstones showed tendencies for elevated HMG-CoA reductase activity and protein content and decreased cholesterol 7 alpha-hydroxylase activities. As anticipated, serum levels of 7 alpha-hydroxycholesterol and squalene paralleled these findings. The patients with gallstones also had significantly increased cytosolic total and free cholesterol levels (P < 0.001), which correlated strongly with increased cytosolic levels of SCP2/nsLTP (r = 0.80, P < 0.001 and r = 0.81, P < 0.001, respectively). CONCLUSIONS The results suggest that intracellular cholesterol transport is enhanced in patients with cholesterol gallstones.

Abstract
We performed screening for osteoporosis for the early detection of a decrease in the bone mineral density. The subjects consisted of 852 inhabitants (308 males and 544 females) aged 40 years or more in Nansei (population, 12, 107) in Mie Prefecture. Interviews, measurement of height and body weight, blood examination, and determination of the bone mineral density by the MD method were performed. In addition, a questionnaire on diet was carried out. The bone mineral density was decreased in 76 subjects (8.9%), of whom females were the majority. Height and body weight were significantly lower in the group with decreased bone mineral density than in the group with normal bone mineral density. The serum calcium (Ca), alkaline phosphatase (ALP), and inorganic phosphorus (P) levels were similar in the two groups. Concerning the family profile, the percentage of subjects living alone was significantly higher (p < 0.05) in the group with decreased bone mineral density (13.5%) than in the group with normal bone mineral density (3.6%). Screening for osteoporosis is still in the trial stage and involves various problems that require further studies. As subjects for screening, females before, during, and immediately after menopause are important.

Abstract
Lipid composition, fluidity, and Na+,K(+)-adenosine triphosphatase (ATPase), Mg(2+)-ATPase, and acetylcholinesterase (AChE) activities of erythrocyte membranes were examined in comparison to plasma lipid composition and lecithin:cholesterol acyltransferase (LCAT) activities in 39 patients with hepatic cirrhosis due to viral hepatitis (Child-Pugh class A, n = 12; class B, n = 13; and class C, n = 14). Plasma LCAT activities decreased and the plasma free-cholesterol to phospholipid molar ratio (C/PL) increased with progressive severity of hepatic cirrhosis. C/PL and fluorescence polarization (inverse of fluidity) of erythrocyte membranes also increased with disease progression (C/PL: Child-Pugh A, 0.911 +/- 0.010; B, 0.941 +/- 0.011; C, 0.979 +/- 0.028; and normal, 0.798 +/- 0.010; fluorescence polarization: Child-Pugh A, 0.348 +/- 0.002; B, 0.351 +/- 0.002; C, 0.355 +/- 0.002; and normal, 0.340 +/- 0.002). There was a correlation between C/PL and fluorescence polarization of erythrocyte membranes (r = .629, P < .001). Na+,K(+)-ATPase activity of erythrocyte membranes did not differ between cirrhotic patients and normal subjects. On the other hand, Mg(2+)-ATPase activity decreased in Child-Pugh C cirrhosis. AChE activity was decreased in Child-Pugh A cirrhosis, and decreased further in Child-Pugh B and C cirrhosis. AChE and Mg(2+)-ATPase activities correlated inversely with fluorescence polarization (r = -.652, P < .001 and r = -.381, P < .01, respectively).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We examined left ventricular (LV) diastolic pulsus alternans associated with systolic pulsus alternans in a patient with hypertrophic cardiomyopathy. Alternation in abnormal LV diastolic pressure waveforms persistently declining into mid-diastole (incomplete relaxation) and normal diastolic pressure were noted. Diastolic pulsus alternans was not corrected by isoproterenol and may possibly be independent of systolic pulsus alternans.

Abstract
To investigate which time constant of isovolumic left ventricular pressure (LVP) decay is the most sensitive measure in acute myocardial ischemia, the time constant of isovolumic relaxation (IR) was calculated by two different models, the semilogarithmic model assuming a zero of LVP decline (TL) and an exponential model (Texp) with an asymptote (extrapolated baseline pressure to which LVP would fall if decay continued indefinitely), in 10 patients before and during ergonovine-induced vasospastic angina. Two time constants were derived from the exponential method as the times for LVP at peak negative dP/dt to decline by 1/e (Texp (1/e)) and by one half (Texp (1/2)). Three changes in LVP during isovolumic relaxation were analyzed and fitted to the two models described above: the LVP from the peak negative dP/dt 1) to when LVP fell to 5 mmHg above LV end-diastolic pressure (EDP), 2) until 40 msec had passed, and 3) to the LVP level 5 mmHg above LVEDP during coronary spasm. There were significant increases in TL, Texp (1/e) and Texp (1/2) in each period of the LVP during vasospastic angina. However, no significant change in Texp or asymptote was observed during angina. We concluded that TL measured by the semilogarithmic model assuming a zero of LVP decline and Texp (1/e) or Texp (1/2) derived from the exponential model are adequately sensitive for detecting acute myocardial ischemia due to coronary spasm.

Abstract
Glucagon, a potent inducer of urea cycle enzymes, was administered subcutaneously, at a dose of 0.5 mg once a day, for 7 days to two citrullinemic patients. During this period, plasma NH3 levels in case 1 decreased significantly (P < 0.05 compared to levels before administration) and daily urinary excretion of urea N increased significantly (P < 0.05). For 1 week after the cessation of administration, the daily urinary excretion of urea N was significantly higher than the level before administration (P < 0.05), the plasma citrulline level during glucagon administration was lower than that before administration. In case 2, glucagon administration also decreased the plasma NH3 level (although the decrease was not statistically significant), and significantly increased daily urinary excretion of urea N (P < 0.05 compared to levels before administration). For 1 week after the cessation of glucagon administration the plasma citrulline level was significantly lower than that before administration (P < 0.05). These results indicate that glucagon significantly increases the urinary excretion of urea in the late onset form of argininosuccinate synthetase deficiency and that it may also decrease plasma NH3 levels in some patients with the deficiency.

Abstract
3-Hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitor is known to have an inhibitory effect on cell growth in addition to a cholesterol-lowering effect. This study examined the effect of pravastatin, a potent inhibitor of HMG-CoA reductase, on the survival of AH130 hepatoma-bearing rats. Pravastatin (1, 2, or 8 mg/kg body weight) was intraperitoneally injected once a day into tumor-bearing rats. The difference in the survival curves was significant between the controls and the rats treated with 8 mg/kg of pravastatin (P < 0.019 by logrank test) but not between the controls and the rats treated with 1 or 2 mg/kg of the inhibitor. The tumor volume was significantly decreased in the rats treated with 8 mg/kg of pravastatin (P < 0.05). These observations showed that intraperitoneal injection of pravastatin could improve the survival of AH130 hepatoma-bearing rats and had an inhibitory effect on the growth of the ascites form tumor.

Abstract
This study was undertaken to determine whether S-adenosyl-L-methionine (SAMe) changes the lipid composition and fluidity of erythrocyte membranes in chronic liver disease. SAMe was administered intravenously at a daily dose of 600 mg for 2 weeks to 10 patients; 6 patients with cirrhosis and four with primary biliary cirrhosis. The elevated free cholesterol to phospholipid molar (C/PL) ratio of the erythrocyte membranes of the patients (0.857 +/- 0.018) significantly decreased after the administration of SAMe (1 week, 0.823 +/- 0.021; 2 weeks, 0.823 +/- 0.013). In all of the four patients whose erythrocyte membrane fluidity was measured, fluidity improved with the administration of SAMe and correlated with the C/PL ratio of the membranes. These results suggest that SAMe decreases the C/PL ratio of erythrocyte membranes and thus improves membrane fluidity in chronic liver disease.

Abstract
Nonspecific lipid transfer protein (nsLTP) partially purified from human liver stimulated human microsomal cholesterol 7 alpha-hydroxylase activity. Addition of the nsLTP preparation to the reaction mixture enhanced the activity two-fold. Treatment of the nsLTP preparation with anti-rat nsLTP antiserum, which cross-reacts with human nsLTP, reduced the 7 alpha-hydroxylase-stimulating ability. These observations suggested that nsLTP plays a role in regulating the 7 alpha-hydroxylase activity in the human liver. 7 alpha-Hydroxylase activity in eight patients with cholesterol gallstones (4.7 +/- 1.6 pmol/min per mg microsomal protein) was significantly lower than that in five controls (7.9 +/- 3.4) (P less than 0.05). The amount of nsLTP in the cytosolic fraction (105,000 X g supernatant) of human liver was determined by dot-blotting immunoquantitation with the antiserum. The cytosolic level of nsLTP in the liver of the patients (716 +/- 239 cpm/3 micrograms protein) was higher than that in the controls (438 +/- 184) although the difference between the two groups was not statistically significant. This suggested that control of the cytosolic level may be affected in patients with cholesterol gallstones.
