Purpose: DepoDur® is a single-dose extended-release morphine injection into the epidural space. It is not commonly used, but has many advantages over traditional analgesic regimens. We analyzed a number of these advantages in our case series in the context of the colorectal enhanced recovery program (ERP) and aimed to show that the ERP could be further enhanced by using DepoDur®. Methods: We conducted a prospective audit of all patients undergoing open and laparoscopic colorectal procedures where DepoDur® was used between July 2010 and April 2012. Validated pain scores were used, and primary outcome measures were resting and dynamic pain, mobilization, and need for additional analgesia. Results: Two hundred eighty patients were included in the case series. Good pain control was seen at 24 and 48 hours. Eighty-one percent of the patients required simple analgesia alone at 24 hours, and 62% required simple analgesia (paracetamol +/– nonsteroidal anti-inflammatory drugs) alone at 48 hours. Only a minority required additional oramorph and patient-controlled analgesia at 24 and 48 hours (19% at 24 hours and 38% at 48 hours). Seventy-nine percent of the patients were mobilized at 24 hours, and 88% of the patients were mobilized at 48 hours. Conclusion: DepoDur® is an effective alternative to conventional pain management techniques and may have a role in further enhancing the ERP.

Most of the bacterial and other simple non glycosylated recombinant proteins were conventionally produced from IPTG inducible Escherichia coli BL21(DE3). Considering the factors like cost and toxic nature of IPTG, as an alternative, salt inducible Escherichia coli GJ1158 was used in this study for the over production of staphylokinase variant (sak – hirulog) using fed batch fermentation, cost effectively. Optimization of physico chemical factors viz., dissolved oxygen (DO), carbon, nitrogen and phosphate sources on bacterial growth for the production of recombinant sak – hirulog using batch and fed batch fermentation was studied. In batch culture, increased DO at more than 30 % did not influence the enhanced expression of sak – hirulog, but significant improvement was observed in fed batch cultivation. Supplementation of production medium with different nutrient sources like dextrose, yeast extract and dipotassium hydrogen phosphate (K2HPO4) enhanced the sak – hirulog expression in fed batch fermentation process even without disturbing the cell growth by providing 50 % DO. Approximately 1178 mg/L of specific protein was obtained using cost effective modified glucose yeast exgtract (GYE) media devoid of sodium chloride. This study also reports the highest concentration of recombinant protein from salt inducible expression host till to date, which manages to satisfy the production of bifunctional staphaphylokinase variant using economically feasible bacterial expression host Escherichia coli GJ1158.
