The growth, nodulation and nitrogen fixation of Casuarina equ&etifolia were compared at six levels (0~500 mM NaCI) of salinity in sand culture. Dry weight of nodules, shoots and roots and N content of shoots increased at intermediate levels of salinity (50-100 mM) but decreased at 500 mM NaC1. Nodulation occurred at all NaC1 levels, but at 500 mM NaC1 level, the nodule dry weight declined by 50% from the control. Increasing NaC1 concentration of up to 200mM had little effect on the N2-fixation rate, but at 500mM NaCI level the rate decreased to 40% of the control value.

We conducted a retrospective study to evaluate the safety of non‐obstetric surgery during pregnancy by studying 106 pregnant women who underwent non‐obstetric surgery at a regional Australian hospital over a 10‐year period. The study showed that maternal and foetal outcomes were comparable to that of the general population. Subgroup analysis did not demonstrate any statistically significant differences between groups, except for an increased rate of delivery by caesarean section in pregnant women who underwent laparotomy compared to those who underwent laparoscopy.

Omental infarct is a rare cause of an acute abdomen that arises from an interruption of blood supply to the omentum. Here, we present a case of omental infarct in a 67-year-old gentleman with background history of diabetes mellitus who present unusually with a severe acute onset right hypochondrium pain. Examination revealed that he was tender to touch at the right and was having localized guarding. His inflammatory markers were normal. He was successfully treated with laparoscopy surgery and he was subsequently discharged the following day. Omental infarct cases with right hypochondrium pain can sometimes mimicked acute cholecystitis and management includes laparoscopic surgery which can hasten symptoms resolution and reduces hospital stay, however recommendation for surgery has to be balanced with anesthetics risk and complication of the surgery itself.
