1. 65Zn was injected intravenously during transjugular liver biopsy and, from simultaneous hepatic and peripheral venous blood samples, hepatointestinal 65Zn extraction was calculated. Hepatic zinc content was measured in biopsy specimens. 2. On the same occasion samples of liver tissue were taken and their zinc content was measured by atomic absorption spectrophotometry. 3. Seven patients with cirrhosis had significantly lower hepatic zinc content and hepatointestinal zinc extraction than six control patients with mild liver disease. Six patients with chronic hepatitis had a mean hepatointestinal zinc extraction higher than control patients, whereas their mean hepatic zinc content was lower, although the former difference did not achieve statistical significance. 4. These results demonstrate that hepatointestinal extraction of zinc is impaired in cirrhosis, but not in chronic hepatitis.

Abstract. The effect of secretin on calcitonin secretion from the human thyroid gland was studied in 15 patients undergoing thyroid and parathyroid surgery. Secretin was administered into the inferior thyroid artery at two different doses (0.75 and 7.5 CU) and into a peripheral vein at a dose of 75 CU. Blood samples for measurements of calcitonin and calcium were collected from thyroid or peripheral veins. However, neither intraarterially nor iv administered secretin was able to evoke any significant calcitonin response as measured in thyroid or peripheral venous blood. The calcium level was unaffected by secretin. The results demonstrate that secretin does not act as a calcitonin secretagogue in man.

Flame Burn

The use of succinylcholine(SC) in burn patients arerelatively contraindicated for certain period after lesion aged4 days – 10 weeks due to chance of hyperkalemia althoughthere are no systemic data to define what period and whatlevel of K+ is safe. This prospective study was carried out in60 acute burn patients who were admitted in DMCH BurnUnit and undergone surgery within 3 months of lesion. Mostcommon type of burn was flame burn (33%).Mean age ofthe patient was 22.60 ± 9.61, TBSA (Total burn surface area)was 22.17 ± 9.57 and duration of burn was 23.36 ± 19.61.Every patient received standard dose of SC (1.5mg/kg) forintubation. The peripheral venous blood samples for serumK+, Na+, Cl - & HCO3- were drawn before induction and 3minutes after injection of SC. On analysis there were nosignificant change of serum K+ and HCO3- (p > .05), on theother hand serum Na+and Cl- levels were significantlychanged (p<0.05) due to correction of dehydration. In caseof electric burn serum K+ level was raised in every casesbut didn’t cross the normal high level of serum K+ (5.5mEq/l). Haemodynamic parameters like pulse, NIBP, SPO2 andECG were analyzed intra operatively and there were nosignificant change in NIBP and ECG, rather there weresignificant improvement in pulse and SPO2 (p< 0.05).Survival of anaesthetic was 100% and no dysrhythmias ormajor morbidity were found intra operatively. Therefore,these data taken in the context of a compelling case forrapid intubating condition suggest safety in succinylcholineuse in the patients with acute burn.   DOI: http://dx.doi.org/10.3329/jbcps.v30i1.11360   J Bangladesh Coll Phys Surg 2012; 30: 5-9

Abstract We measured parathyrin (PTH) in peripheral venous blood samples and in thyroid veins (both homolateral and contralateral to the lesion) in 13 patients with surgically confirmed parathyroid adenomas. Two different RIAs were used, one specific to the mid-region of the molecule (44-68, M-PTH), the other specific to the carboxy-terminal region (65-84, C-PTH). With the M-PTH assay we established a statistically significant multiple correlation (P less than 0.05) between the PTH concentrations in blood from the peripheral and thyroid veins; no significant correlation was found when we used the C-PTH assay. Our results confirm the superiority of the M-PTH RIA over the C-PTH RIA for study of hormonal secretion in primary hyperparathyroidism.

Cardiovascular Morbidity And Mortality

Introduction. Hypertension (HT) is a common serious condition associated with cardiovascular morbidity and mortality. The pathogenesis of HT is multifactorial and has been widely investigated. Besides the vascular, hormonal, and neurological factors, inflammation plays a crucial role in HT. Many inflammatory markers such as C-reactive protein, cytokines, and adhesion molecules have been studied in HT, which supported the role of inflammation in the pathogenesis of HT. Presepsin (PSP) is a novel biomarker of inflammation. Therefore, the potential relationship between PSP and HT was investigated in this study. Methods. Forty-eight patients with controlled HT and 48 controls without HT were included in our study. Besides routine clinical and laboratory data, PSP levels were measured in peripheral venous blood samples from all the participants. Results. PSP levels were significantly lower in patients with HT than in controls (144.98±75.98 versus 176.67±48.12 pg/mL, p=0.011). PSP levels were positively correlated with hsCRP among both the patient and the control groups (p=0.015 and p=0.009, resp.). However, PSP levels were not correlated with WBC among both groups (p=0.09 and p=0.67, resp.). Conclusions. PSP levels are not elevated in patients with well-controlled HT compared to controls. This result may be associated with anti-inflammatory effects of antihypertensive medicines.

Abstract Aim To compare the number of circulating tumor cells (CTCs) in portal venous blood samples of patients with potentially resectable adenocarcinoma of de distal esophagus and the gastro-esophageal junction (EAC) with the number of CTCs in peripheral venous blood samples. Background and Methods Detection of (CTCs) in potentially resectable (EAC) is rare in peripheral venous blood samples(1). In lung carcinoma patients, the number of circulating tumor cells was more than 300 fold in the pulmonary vein, compared to the number in peripheral venous blood samples (2). In patients undergoing esophagectomy for cancer, peripheral blood was sampled immediately preoperatively and portal vein blood was sampled intraoperatively during abdominal lymph node dissection. Samples were analyzed for CTCs using the parsortix device (ANGLE): a semi-automated microfluidic system that captures cells based on their size and rigidity. A four-color immunofluorescence technique was used and CK positive, CD45 negative, Hoechst positive and morphologically intact cells with the morphology of a CTC were counted manually. The method was previously compared with the commercially available Cellseach® system and no difference in CTC yield between both methods. Results 20 patients with potentially resectable EAC were evaluated. One peripheral venous sample and two portal venous samples were not applicable. In 5 out of 19 peripheral venous samples (26,3%), one or more CTC’s could be detected, while in this was only the case in 3 out of 18 portal venous samples (16.7%). Conclusions The number of detected CTCs in potentially resectable EAC was not increased in portal venous samples compared to peripheral venous samples. Further research is needed on why detection rate of CTCs in potentially resectable EAC is so low and how detection rate could be increased.

Introduction: The aim of our study was to assess association of serum S100A4 protein with ulcerative colitis (UC) and Crohn’s disease (CD). Methods: Study included 118 subjects: 93 patients with CD, 16 with UC and 9 controls. In CD group, 20/93 patients had B1 phenotype, 19/93 B2, 20/93 B3 and 34/93 B2 + B3. L1 involvement was present in 15/93, L2 in 14/93 and L3 in 64/93 patients. Serum S100A4 concentration was investigated in peripheral venous blood samples by means of ELISA. Results: Serum S100A4 was significantly higher in UC (158.6 ± 56.2 ng/mL), p = 0.019 and in CD (154.4 ± 52.1 ng/mL), p = 0.007 compared to controls (104.8 ± 40.5 ng/mL). No difference in S100A4 was revealed between UC and CD, p > 0.05. Serum S100A4 in each CD subgroup (according to behaviour) was significantly higher compared to controls, p < 0.05. Serum S100A4 was significantly higher in L2 (144.6 ± 44.2 ng/mL), p = 0.041 and in L3 (163.0 ± 52.8 ng/mL), p = 0.002 compared to controls and in L3 compared to L1 (126.9 ± 47.6 ng/mL), p = 0.017. Conclusion: Association of serum S100A4 protein with UC and CD was confirmed. In CD, disease behaviour did not influence serum concentration of S100A4 protein. In CD, higher levels of serum S100A4 were observed in patients with ileo-colonic and colonic involvement compared to those with isolated small bowel involvement.
