This study investigated the awareness and attitudes of basic surgical trainees. Trainees were asked to answer
questions from a pre-set questionnaire. Fifty basic surgical trainees from England and Wales were involved in the study. The areas covered were basic knowledge of radiation hazards, use of protective wear, pregnancy test in female trauma victims of reproductive age, and principles of safe radiation. All the questions were asked in the context of orthopaedic trauma surgery. All questions were evidence based. It was unfortunate to notice that basic surgical trainees are lacking in the essential knowledge of ionising radiation.
Most of the trainees are not adhering to radiation safety principle, and are not practising safely. The authors strongly recommend that surgical trainees should have more robust training and information available in this context. And they suggest that it should be provided on local, regional and national basis.

Xanthogranulomatous cholecystitis is a rare histopathological finding and accounts for 1.3% to 5.2% of cases. It closely resembles gallbladder cancer because of its extensive inflammation and involvement of the surrounding organs. We are reporting a case where it presents as an extensive inflammatory mass mimicking gallbladder cancer.

OBJECTIVETo evaluate pharmacologically the traditional use of Diospyros lotus as antipyretic and antinociceptive in various animal models.
METHODSIn vivo experimental models were used in this study. Antipyretic activity of extract/fractions was evaluated in brewer's yeast induced hyperthermic mice while antinociceptive activity was studied in acetic acid induced writhing test at 50 and 100 mg/kg i.p.
RESULTSThe crude extract strongly ameliorated the induced pyrexia during various assessment times. Upon fractionation, the antipyretic effects were strongly augmented by the chloroform and ethyl acetate fractions of the plant. However, hexane and butanol fractions were insignificant in their effect as antipyretic. The extract showed marked inhibition on the noxious simulation induced by post acetic acid injection. The effect was strongly supported by other fraction expect hexane.
CONCLUSIONSIn short, our study scientifically validated the traditional use of the plant as antipyretic.

Two new dimeric naphthoquinones, 5',8'-dihydroxy-6,6'-dimethyl-7,3'-binaphthyl-1,4,1',4'-tetraone (1; Di-naphthodiospyrol D) and 5',8'-dihydroxy-5,8-dimethoxy-6,6'-dimethyl-7,3'-binaphthyl-1,4,1',4'-tetraone (2; Di-naphthodiospyrol E), along with known naphthoquinones diospyrin (3) and 8-hydroxy diospyrin (4) were isolated from the chloroform fraction of extract of Diospyros lotus roots. Their structures were elucidated by advanced spectroscopic analyses, including HSQC, HMBC, NOESY, and J-resolved NMR experiments. The fractions and compounds 1-4 were evaluated for urease activity and phosphodiesterase-I, carbonic anhydrase-II and α-chymotrypsin enzyme inhibitory activities. Compounds 1 and 2 and their corresponding fractions showed significant and selective inhibitory effects on urease activities. The IC values of 1 and 2 were 260.4 ± 6.37 and 381.4 ± 4.80 µmol·L, respectively, using thiourea (IC = 21 ± 0.11 µmol·L) as the standard inhibitor. This was the first report demonstrating that the naphthoquinones class showed urease inhibition.

In this study, a novel phthalic acid ester (1) and a known iridoid glycoside (2) were
isolated from the root bark of Anthocleista vogelii. The structures of the novel compound and
iridoid glycoside were elucidated on the basis of their chemical and spectral data (UV, FT-IR,
EI-MS, 1D and 2D NMR) and found to be phthalic acid ester, 4-ethyl-6-propyl-4,5,6,7-tetrahydro-
3H-2,8-benzodioxacycloundecine-1,9-dione (1) and sweroside (2). The compounds were
evaluated for their in vitro inhibitory activities against pancreatic lipase, α-amylase and α-
glucosidase, and in vivo laxative activity in rats. The metabolite phthalic acid ester (1)
exhibited moderate inhibitory activity against pancreatic lipase (IC50 = 24.43 ± 0.096 μg/mL)
and relatively good activity against α-glucosidase (IC50 = 10.28 ± 0.015 μg/mL). Sweroside (2)
displayed weak activity against α-glucosidase (IC50 = 40.28 ± 0.063 μg/mL) but significantly
(p<0.05) increased the feacal output of the treated animals compared to the normal and
sodium picosulfate controls.
