Abstract The hemodynamic determinants of myocardial oxygen demand measured were heart rate (HR), systolic blood pressure (BP), and rate pressure product (RPP). This study aimed to evaluate the impact of lipid profile, cardiac biomarkers, and serum angiotensin-converting enzyme (ACE) activity, oxidative stress (plasma malondialdehyde, MDA; conjugated diene, DC), and antioxidant status (glutathione peroxidase, GPx) on BP. Three hundred and six non-ST-elevated myocardial infarction (NSTEMI) patients compared to 410 healthy controls. The diastolic and systolic BP was correlated positively with serum ACE activity. The rate pressure product (RPP) was correlated negatively with Fasting glucose (r= -0.144; p = 0.012), HbA1c (r= -0.117; p = 0.041) and GPx activity (r= -0.148; p = 0.009), and positively with smoking (r = 0,197; p = 0.001), BMI (r = 0,219; p = 0.001), peak cTnI (r = 0.131; p = 0.022), serum ACE activity (r = 0,190; p = 0.001) and DC level (r = 0.189; p = 0.001) in NSTEMI patients. Regarding healthy controls, no correlation was found between the diastolic or systolic BP with serum ACE activity, peak cTnI, MDA, DC level, GPx activity, and lipid parameters. The existence of a specific correlation between the rate pressure product, diastolic and systolic BP and, lipid profile, serum ACE activity and, cardiac biomarkers, oxidative stress, and antioxidant status increase the NSTEMI risk on patients.

Physiological Variations

Abstract Angiotensin-converting enzyme (ACE) was measured in serum of 187 healthy children between the ages six months and 18 years. Results were pooled for five-year age intervals and compared with the reference values for adults that we previously determined [Clin Chem 1986;32:884-6). Results for each age group were also studied as a function of sex. Children had higher ACE activities in serum than did adults (P less than 0.001), but these activities were age-related only from age four to 18 years. Adolescents showed sex-related differences, with higher serum ACE activities in boys than in girls (P less than 0.05). Both sex- and age-related differences may be related to a steroid hormonal regulation of ACE biosynthesis. We also verified that children with sarcoidosis (n = 20) had significantly increased serum ACE activity. Such physiological variations in serum ACE activity must be taken into account for diagnosing sarcoidosis in children, for following the course of the disease, and for evaluating the accuracy of therapy.

Objectives The aims of this study were to investigate the pharmacodynamics of alacepril and to determine the appropriate dose for clinical usage in cats. Methods Six experimental cats were used. Each cat received alacepril orally at a single dose of 1 mg/kg, 2 mg/kg and 3 mg/kg. Blood samples were collected before administration and at 2, 4, 6, 8, 12, 24, 36, 48 and 72 h after administration to measure serum angiotensin converting enzyme (ACE) activity. Systolic blood pressure was also measured at the same time point. Results Dose-dependent inhibition of ACE activity was observed. Doses of 2 mg/kg and 3 mg/kg alacepril were considered to effectively inhibit ACE activity. There were no significant differences in systolic blood pressue among groups at any time point. Conclusions and relevance Alacepril 2–3 mg/kg q24h may be an appropriate dosage for clinical use in cats.

AbstractBackgroundVitiligo, a skin disorder is viewed as a multifactorial process with major role of reactive oxygen species in concert to destroy or incapacitate melanocytes. In Unani system of medicine the treatment of Bars (Vitiligo) starts with removal of harmful materials from the body with Munzij and Mushil (MM), a poly herbal Unani formulation.MethodsHerein, oxidative stress related parameters as MDA, SOD, GPx and CAT have been estimated in the 21 clinically diagnosed Vitiligo in-patients and subsequently these parameters were evaluated during and after administration of MM therapy and compared with 21 healthy subjects.ResultsThere was significant difference in the parameters viz., SOD (p<0.001) and CAT (p<0.005) activity at the baseline with no statistical significant difference in MDA and GPx activity among Vitiligo subjects and controls. After MM therapy there was no statistical significant difference among the values of these parameters in Vitiligo subjects.ConclusionsThe results suggest that there is imbalance in the oxidant-antioxidant status of Vitiligo subjects and the MM therapy is not found to significantly change the levels of oxidative stress related parameters.

Abstract Background To explore the clinical significance of serum angiotensin-converting enzyme (ACE) activity in coronavirus disease 2019 (COVID-19). Methods In this retrospective study, a total of 136 consecutive patients with confirmed COVID-19 were recruited. Demographic and clinical data were recorded. The serum ACE activity was measured at baseline and during the recovery phase, and its relationship with clinical condition was analyzed. Results Of the 136 patients with confirmed COVID-19, the 16 severe patients were older and had a higher body mass index (BMI) and proportion of hypertension than the 120 nonsevere patients. In comparison to those of normal controls, the baseline serum ACE activities of subjects in the severe group and nonsevere group were decreased, with the lowest level in the severe group. However, the serum ACE activity increased in the recovery phase, and there were no significant differences among the severe group, nonsevere group and normal control group. Conclusion Serum ACE activity could be used as a marker to reflect the clinical condition of COVID-19 since low activity was associated with the severity of COVID-19 at baseline, and the activity increased with the remission of the disease.

Background and Objective.Oxidative stress is intimately associated with many diseases, including chronic obstructive pulmonary disease (COPD). Study objectives include a comparison of the oxidative stress, antioxidant status, and lipid profile between COPD patients and controls and evaluation of the effect of spirulina intervention on oxidative stress, antioxidant status, and lipid profile of COPD patients.Methods.30 patients with COPD and 20 controls with no respiratory problems were selected. Global Initiative for Chronic Obstructive Lung Disease criteria were served as the basis of COPD diagnosis. The serum content of malondialdehyde (MDA), lipid hydroperoxide, glutathione (GSH), vitamin C, cholesterol, triglyceride (TG), and high density lipoprotein (HDL) was measured. The activity of superoxide dismutase (SOD), catalase (CAT), and glutathione-s-transferase (GST) was also measured. Two different doses, (500 × 2) mg and (500 × 4) mg spirulina, were given to two groups, each of which comprises 15 COPD patients.Results.All targeted blood parameters have significant difference(P=0.000)between COPD patients and controls except triglyceride (TG). Spirulina intake for 30 and 60 days at (500 × 2) mg dose has significantly reduced serum content of MDA, lipid hydroperoxide, and cholesterol(P=0.000)while increasing GSH, Vit C level(P=0.000), and the activity of SOD(P=0.000)and GST(P=0.038). At the same time, spirulina intake for 30 and 60 days at (500 × 4) mg dose has favorable significant effect(P=0.000)on all targeted blood parameters except for HDL(P=0.163).
