Flap Survival

Abstract Background The present study was design to investigate the effect of isoliquiritin (ISL) pretreatment on multi-territory perforator flap survival and blood vessels of Choke II zone in rats.Methods A total of 80 adult Sprague-Dawley (SD) rats were randomly divided into ISL group and normal saline group, and subsequently and subjected to multi-territory perforator flap operations on the left flank. Afterwards, rats in ISL group were intraperitoneally injected with ISL, and rats from normal saline group were intraperitoneally injected with equal amount of normal saline. After seven days, the surviving flap area was calculated, the density of microvessels and (vascular endothelial growth factor,VEGF)were measured in Choke II zone. In addition, blood vessels of the flap were subjected to lead oxide-gelatin radiography.Results The flap survival area was significantly enhanced in rats from the ISL group compared with that from the saline group (P < 0.01). HE staining indicated significantly higher microvascular density in Choke II zone in the ISL group (P < 0.01). Immunohistochemistry and Western blot assays showed that the expression of VEGF in the ISL group was significantly higher than that in the control group (P < 0.01). Moreover, the vascular structure in Choke II zone of the flap was clearer, with more new blood vessels and more complete vascular structure in the potential zone from the ISL group, in comparison with those from the normal saline group.Conclusion ISL is beneficial to the multi-territory perforator flap survival in rats.

This study investigated splenic status changes in weaned Sprague-Dawley rats induced by lipopolysaccharide. There were forty 26-day-old rats selected randomly and equally divided into two groups. The treatment group received daily single doses of lipopolysaccharide, and the control group was treated with normal saline. We conducted haematoxylin-eosin staining, immunohistochemical staining and semi-quantitative optical density analysis for both groups on the 29th, 32nd, 35th and 38th days after treatment. The results indicated that splenic marginal zone in the lipopolysaccharide group was thinner or disappeared compared to that of the saline group. However, the periarterial lymphoid sheath and the diameters of splenic lymphoid follicles appeared thicker and wider than those in the saline group (P less than 0.05). The expression of interleukin-1 beta, interleukin-6 and tumour necrosis factor alpha was mainly localized within the periarterial lymphoid sheath and splenic lymphoid follicles in the lipopolysaccharide treated rats. The integrated optical density and the average optical density in the lipopolysaccharide group were greater than those in the normal saline treated group (P less than 0.05). In conclusion, splenic immune function is probably strengthened by altering microstructures and releasing pro-inflammatory cytokines following lipopolysaccharide treatment.

Background: Diabetes mellitus is a chronic metabolic disorder that develops due to insulin deficiency or insulin resistance. Recent animal and human studies have reported bromocriptine to be effective in the management of type 2 diabetes mellitus. The present study was done to evaluate the antihyperglycemic effect of bromocriptine in dexamethasone induced hyperglycemic rats.Methods: Male wistar rats were used and divided into 5 groups. Dexamethosone was used to induce hyperglycemia in group B-E. Group A was the untreated control group, group B was the standard control group, group C was the oral 10 mg/kg of bromocriptine dissolved in 0.9% normal saline, group D was the oral 20 mg/kg metformin dissolved in 0.9% normal saline, group E was the oral 10 mg/kg bromocriptine+20 mg/kg metformin dissolved in 0.9% normal saline. Fasting blood glucose, post prandial blood glucose and body weight was estimated on day 1, 15, 30.Results: It was seen that dexamethasone induced hyperglycemia and increase in body weight in male wistar rats, which were significantly controlled by oral bromocriptine and bromocriptine with metformin combination.Conclusions: Results obtained from this study showed that bromocriptine can be a promising drug with novel mechanism to treat type 2 diabetes mellitus.

Background: Thermoregulatory system coordinates defenses against environmental temperature to maintain internal core temperature within a narrow range, thus optimizing normal body function and homeostasis in humans. Anaesthetic induced thermoregulatory impairment and hence hypothermia in cold environments. Shivering is an important complication of hypothermia. Shivering is an involuntary, oscillatory muscular activity that augments metabolic heat production upto 600% above basal level to increase temperature. It is associated with substantial adrenergic activation, discomfort and can double or even triple oxygen consumption and carbon dioxide production. Potent anti-shivering properties have been attributed to numerous drugs including biogenic monoamines, cholinomimetics, cations, endogenous peptides and possibly N-methyl-D- aspartate (NMDA) receptor antagonists like ketamine, tramadol and clonidine. Aim: To evaluate the effectiveness of prophylactic use of intravenous ketamine, clonidine and tramadol in control of shivering and to note any side-effects of the drugs used. Methods: A total number of 120 ASA I and 2 patients of either sex belonging to age group 18-60 years posted for Lower Abdomen and Lower Limb surgeries under subarachnoid block were divided into four groups of 30 each. Group P (control group): Patients received 10mL of normal saline IV as placebo. Group K: Patients received Inj. Ketamine 0.5mg/kg BW IV diluted to 10ml in Normal Saline. Group C: Patients received Inj. Clonidine 75mcg IV diluted to 10ml in Normal Saline. Group T: patients received Inj. Tramadol 0.5mg/kg BW IV diluted to 10ml in normal saline. Results: We conclude that giving Ketamine 0.5mg/kg,Clonidine 75mcg or tramadol 0.5mg/kg i.v. prophylactically just before subarachnoid block significantly decreased the incidence of shivering without causing any major side effects. Conclusion: Ketamine, Tramadol or Clonidine decrease shivering during spinal anesthesia.

Abstract Background: Previous studies demonstrate that long-tern microgravity induces multi-organ injury and dysfunction, including the dorsal root ganglia (DRG) damage. This study investigated oral pyruvate protective effects on lumbar 5 (L5) DRG nerve tissues in rats subjected to hindlimb unweighting (HU).Results: Male Sprague-Dawley rats were randomly assigned to four groups (n=10): control group (Group CON), suspension group (Group SUS), normal saline group (Group SAL) and sodium pyruvate group (Group PYR), respectively. The rats of SUS, SAL and PYR groups were simulated with microgravity by tail suspension of HU for 8 weeks. Rats in Groups SAL and PYR fed with normal saline and pyruvate saline, respectively. Histopathological and immunofluorescence examinations were conducted and levels of glial cell line-derived neurotrophic factor (GDNF), glial fibrillary acidic protein (GFAP), ATP and ATPase were measured in DRG tissues; L5 spinal cord scans were also carried out in rats following HU. Results showed that the HU resulted in significant alterations in DRG nerve tissues’ structure and function in Groups SUS and SAL, whereas morphological changes were not significantly distinguished between Group PYR and Group CON; GDNF, GFAP, ATP and ATPase levels were mostly preserved in Group PYR, but still worse than in Group CON. The significance of oral pyruvate protection against DRG injury following HU and the dose and formula of oral pyruvate solutions were discussed for use in astronauts’ spaceflight.Conclusions: oral pyruvate effectively protected L5 DRG from pathological alterations and dysfunction induced by the HU in rats. Further studies and clinical trials are warranted.

Various studies revealed that what matters for women during labour is short duration painless labour which results to better birth outcome. Various drugs and methods used to hasten labour both traditionally and in modern obstetrics to minimize the risks of prolonged labour. To assess the effects of Hyoscine Butylbromide in shortening active phase of the first stage of labour in term pregnant women. This study was designed as a double-blind, randomized, controlled, clinical trial comparing two groups of 200 term pregnant women, where by the intervention group received 20mg of hyoscine butylbromide intravenously while the control group received 1ml normal saline via the same route during the active phase of labour with cervix dilatation confirmed to be 4-5 centimeters. The progress of labour for both groups was closely monitored and documented according to the principles of active management of labour. Both women and birth attendants were blinded on the contents of the syringes. The mean rate of cervical dilatation in cm per hour in hyoscine group was 2.6±0.9 and in normal saline was 1.8±0.8 the mean difference was statistical significance (p=<0.05). The duration of the active phase of the first stage of labour was shorter in hyoscine group (190.1±128.9) minutes compared to 266.8±123.2 minutes of normal saline group (P=0.001). The characteristics of women including mean age, gestational age and parity were similar in both groups. The Apgar score of hyoscine group and normal saline group were similar and the differences were not statistically significant. Hyoscine butylbromide is effective drug in shortening the active stage of the first stage of labour in term pregnant women. The drug has no effect during the second and the third stage of labour and no obvious adverse effect to mothers and newborn.

Objective: To study the effectiveness of prophylactic ephedrine to prevent hypotension caused by induction of anesthesia with propofol and sufentanil in elderly hypertensive patients. Methodology: 70 elderly ASA grade II-III hypertensive patients undergoing elective general anesthesia were randomized into two groups to receive either intravenous ephedrine,100 ug/kg in 5ml normal saline (Group B), or an equal volume of normal saline (Group A) before induction. Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP) and Heart Rate (HR) were recorded at T0 (after entry to the operating room), T1 (1 min after induction), T2 (2 min after induction), T3 ( 3 min after induction), T4 (4 min after induction), T5 (when intubated), T6 (2 min after intubation), and T7 (at the start of the procedure), as well as the incidence of hypotension and bradycardia. Results: SBP, DBP and HR were not significantly different at T0 and were significantly different at T1 to T7 after anesthesia induction. There were statistically significant effect on hypotension and bradycardia between the two groups and group B have a lower risk of hypotension and bradycardia relative to group A. SBP and DBP decreased significantly after induction in both groups. HR decreased significantly in group A while increased in group B. Conclusion: Ephedrine pretreatment can minimize hypotension and bradycardia caused by propofol and sufentanil during the induction of general anesthesia in elderly patients with hypertension.

Background: Nasal packing is commonly done after septal surgeries. Nonabsorbable nasal pack is used to minimize bleeding from surgery site, support the mucoperichondrial flaps, and minimize the risk of formation of septal hematomas and adhesions. However, these materials cause pain and discomfort in-situ as well as during removal. This study was done to evaluate the effect of 2% lignocaine rehydration of nasal pack on pain during pack removal. Methods: This prospective study was conducted on 60 patients who had undergone septoplasty. The patients were divided into 2 groups: Lignocaine and Normal saline group, with 30 patients each. In the Lignocaine group, 2.5 ml of 2% of lignocaine was diluted with 2.5 ml of distilled water and was injected into the nasal pack; and in Normal saline group, 5 ml of normal saline was injected into the nasal pack. Nothing was injected to the left nostril, which acted as a control, in both groups. All patients were asked severity of pain during removal of nasal packing by VAS. Results: In lignocaine group, mean pain score was 3.73 ± 1.63 on lignocaine side and 6.23 ± 1.69 on control side (U=109.5, p<0.001). In Normal saline group, it was 6.5 ± 1.7 on normal saline side and 6.23 ± 1.96 on control side (U=425.5, p=0.711). On comparing VAS between lignocaine and normal saline group, pain was significantly lower in the lignocaine group (U=112.5, p<0.001) Conclusion: Rehydrating nasal pack with 2% topical lignocaine is a useful method to reduce pain during nasal pack removal.

Background: Shivering is an undesirable complication following general anesthesia and spinal anesthesia, whose early control can reduce postoperative metabolic and respiratory complications. Therefore, this study aims to compare the effects of prophylactic injection of ketamine and pethidine on postoperative shivering. Methods: This double-blind clinical trial was performed on 105 patients with short-term orthopedic and ENT surgery. The patients were randomly divided into three groups; 20 minutes before the end of the surgery, 0.4 mg/kg of pethidine was injected to the first group, 0.5 mg/kg of ketamine was injected to the second group, and normal saline was injected to the third group. After the surgery, the tympanic membrane temperature was measured at 0, 10, 20, and 30 minutes. The shivering was also measured by a four-point grading from zero (no shivering) to four (severe shivering). Data were analyzed by one-way ANOVA, Kruskal Wallis, Chi-square and Pearson correlation. Results: The mean age of patients was 35.8+/-11.45 years in the ketamine group, 34.8+/-11.64 years in the normal saline group, and 33.11+/-10.5 years in the pethidine group. The one-way ANOVA showed no significant difference in the mean age between the three groups (P=0.645). The incidence and intensity of shivering were significantly higher in the normal saline group than in the ketamine and pethidine groups (p=0.001). However, there was no significant difference in the incidence and the intensity of shivering between the ketamine and the pethidine groups (p=0.936). Conclusion: The results showed that the 0.5 mg/kg of ketamine could control the post-anesthetic shivering.

Background Caudal epidural analgesia with bupivacaine is very popular in paediatric anaesthesia for providing intra- and postoperative analgesia. Several adjuvants have been used to prolong the action of bupivacaine. Objectives To compare the efficacy of ketamine, fentanyl and clonidine in terms of quality and duration of analgesia they produce when added with caudal bupivacaine by single shot technique in children. Methods Eighty children, age one to ten years, undergoing sub-umbilical surgery, were prospectively randomized to one of four groups: caudal analgesia with 0.75 ml/kg of 0.25% bupivacaine in normal saline (Group B) or caudal analgesia with 0.75 ml/kg of 0.25% bupivacaine with 1 μg/kg of clonidine in normal saline (Group BC) or caudal analgesia with 0.75ml/kg of 0.25% bupivacaine with ketamine 0.5mg/kg (Group BK) or caudal analgesia with 0.75ml/kg of 0.25% bupivacaine with fentanyl 1mcg/kg (Group BF). Post-operative pain was assessed for 24 hours using the FLACC scale. Results The mean duration of analgesia was significantly longer in Group BC (629.06 ± 286.32 min) than other three groups P < 0.05. The pain score assessed using FLACC scale was compared between the four groups, and children in Group BC had lower pain scores, which was statistically significant. The requirement of rescue medicine was lesser in Group BC. Clonidine in a dose of 1 μg/kg added to 0.25% bupivacaine for caudal analgesia, during sub-umbilical surgeries, prolongs the duration of analgesia of bupivacaine, without any side effects in compare to fentanyl or ketamine. Conclusion We conclude that clonidine in a dose of 1 μg/kg, added to 0.25% bupivacaine for caudal analgesia and administered as a 0.75 ml/kg mixture in children, for sub-umbilical surgery, significantly prolongs the duration of post-operative analgesia when compared to 0.75 ml/kg of 0.25% bupivacaine in normal saline than 0.75 ml/kg of 0.25% bupivacaine with ketamine 0.5 mg/kg or 0.75 ml/kg of 0.25% bupivacaine with fentanyl 1 mcg/kg or 0.75 ml/kg of 0.25% bupivacaine alone, without any side effects.

Objective. The present study was performed to investigate the effect of N-desulfated heparin on basic fibroblast growth factor (bFGF) expression, tumor angiogenesis and metastasis of gastric carcinoma.Methods. Human gastric cancer SGC-7901 tissues were orthotopically implanted into the stomach of NOD SCID mice. Twenty mice were randomly divided into two groups which received either intravenous injection of 0.9% NaCl solution (normal saline group) or 10 mg/kg N-desulfated heparin (N-desulfated heparin group) twice weekly for three weeks. In vitro, human gastric carcinoma SGC-7901 cells were treated with N-desulfated heparin in different concentration (0.1 mg/mL, 1 mg/mL, N-desulfated heparin group), and treated with medium (control group).Results. In vivo, the tumor metastasis rates were 9/10 in normal saline group and 2/10 in N-desulfated heparin group (P<0.05). The intratumoral microvessel density was higher in normal saline group than in N-desulfated heparin group (P<0.05). bFGF expression in gastric tissue was inhibited by N-desulfated heparin (P<0.05). There was no bleeding in N-desulfated heparin group. In vitro, N-desulfated heparin inhibited significantly bFGF protein and mRNA expression of gastric carcinoma cells (P<0.05).Conclusions. N-desulfated heparin can inhibit the metastasis of gastric cancer through inhibiting tumor bFGF expression and tumor angiogenesis with no obvious anticoagulant activity.
