ABSTRACT
The potential application of Truffle (Terfeziaceae) and Desert Date tree (Balanites aegyptiaca) for modulating the diabetesmellitus related symptoms has gained much interest. However, less firm evidence has come from data to increase theunderstanding of the mechanism by which Truffle and Balanites protect pancreatic β-cells. The present study aimed toevaluate the effect of methanolic extract of Truffle and Balanites aegyptiaca on the fasting blood glucose (FBG) level; thechanges in pancreatic histology as well as the changes in iNOS and IL-1β genes expression level among STZ induceddiabetic rats which might help in better clarification of possible mechanisms beside the beneficial effects of the studiedplants on diabetes. The elevation of the FBG level, pathological pancreatic changes and the level of both IL-1β and iNOSgene expressions in diabetic rats were observed in comparison with negative control rats. This increase was declinedsignificantly due to the administration of Truffle and Balanites extracts. All of the studied parameters did not completelyreverse to the normal levels as compared with negative control rats. The obtained results concluded that the beneficial effectof Truffle and Balanites aegyptiaca on STZ-induced diabetes was at least partly due to the reduction of IL-1β and iNOS geneover the expression which can have a protective effect on β cell.
ABSTRACT
Abstract Objectives: We conducted this study to investigate the safety and analgesic efficacy of the addition of Ketamine to Bupivacaine in bilateral extra-oral infra-orbital nerve block in children undergoing cleft lip surgeries. Methods: Sixty patients were randomly allocated into two groups (n = 30), Group B received infra-orbital nerve block with 2 mL of 0.25% Bupivacaine and Group BK received 0.5 mg.kg-1 Ketamine for each side added to 1 mL of 0.5% Bupivacaine solution diluted up to 2 mL solution to 0.25% Bupivacaine concentration. Assessment parameters included; hemodynamics, recovery time, time to first oral intake, postoperative Faces Legs Activity Cry Consolability (FLACC) scores, Four-point Agitation scores, analgesic consumption and adverse effects. Results: Patients in Group BK showed lower postoperative FLACC scores during all recorded time points (p < 0.0001). Two patients in Group BK versus 12 in Group B requested for postoperative rescue analgesia (p < 0.001). There were no differences between groups in time, minutes (min), to first request for rescue analgesia. Patients in Group BK reported lower analgesic consumption (366.67 ± 45.67 vs. 240.0 ± 0.0 mg, p < 0.04). The time to first oral intake was significantly reduced in Group BK (87.67 ± 15.41 vs. 27.33 ± 8.68 min, p < 0.001). Lower postoperative Agitation scores were recorded in Group BK patients that reached a statistical significance at 45 min (0.86 ± 0.11 vs. 0.46 ± 0.16, p < 0.04) and in the first hour (h) postoperatively (1.40 ± 0.17 vs. 0.67 ± 0.14, p < 0.003). Higher parent satisfaction scores were recorded in Group BK (p < 0.04) without significant adverse effects. Conclusions: The addition of Ketamine to Bupivacaine has accentuated the analgesic efficacy of infra-orbital nerve block in children undergoing cleft lip repair surgeries.
Resumo Objetivos: Realizamos este estudo para avaliar a segurança e eficácia da analgesia com a adição de cetamina à bupivacaína em bloqueio do nervo infraorbitário, bilateral e extraoral, em crianças submetidas à cirurgia de lábio leporino. Métodos: Foram randomicamente alocados 60 pacientes em dois grupos (n = 30): o Grupo B recebeu bloqueio do nervo infraorbitário com bupivacaína a 0,25% (2 mL) e o Grupo BC recebeu bloqueio com cetamina (0,5 mg.kg-1) em cada lado, mais a adição de 1 mL de solução de bupivacaína a 0,5% diluída até 2 mL da concentração a 0,25%. Os parâmetros de avaliação incluíram: hemodinâmica, tempo de recuperação, tempo até a primeira ingestão oral, escores da escala FLACC (que avalia a expressão facial [Face], os movimentos das pernas [Legs], a atividade [Activity], o choro [Cry] e a consolabilidade [Consolability]), escores de agitação em escala de quatro pontos, consumo de analgésicos e efeitos adversos no pós-operatório. Resultados: Os pacientes do Grupo BC apresentaram escores FLACC mais baixos em todos os momentos mensurados no pós-operatório (p < 0,0001). Dois pacientes do Grupo BC versus 12 do Grupo B solicitaram analgesia de resgate no pós-operatório (p < 0,001). Não houve diferenças entre os grupos em relação ao tempo até a primeira solicitação de analgesia de resgate. Os pacientes do Grupo BC relataram consumo menor de analgésicos (366,67 ± 45,67 vs. 240,0 ± 0,0 mg, p < 0,04). O tempo em minutos (min) até a primeira ingestão oral foi significativamente reduzido no Grupo BC (87,67 ± 15,41 vs. 27,33 ± 8,68 min, p < 0,001). Escores mais baixos de agitação no pós-operatório foram registrados para os pacientes do Grupo BC, com significância estatística no tempo de 45 min (0,86 ± 0,11 vs. 0,46 ± 0,16; p < 0,04) e na primeira hora de pós-operatório (1,40 ± 0,17 vs. 0,67 ± 0,14; p < 0,003). Índices mais altos de satisfação dos pais foram registrados no Grupo BC (p < 0,04), sem efeitos adversos significativos. Conclusões: A adição de cetamina à bupivacaína acentuou a eficácia analgésica do bloqueio do nervo infraorbitário em crianças submetidas à cirurgia de correção de lábio leporino.
