Cactus spines can easily puncture the skin with only minor pressure. Removal of the offending cactus spine is the treatment of choice; however, it is very difficult, even with tweezers. A 17-year-old Korean girl presented for evaluation of multiple purple-colored macules and papules on the left cheek and left thumb. Two months earlier, she had pricked her finger and face on cactus spines while volunteering in Haiti. An ultrasound identified wedge-shaped echogenic materials suspected as cactus spines. We recommended surgical removal of the spines, but she vehemently refused. We then advised her to take amoxicillin/clavulanic acid and undergo regular follow-up. During the follow-up period, the spines dislodged spontaneously for easy removal and the patient removed them with tweezers. The lesions actually improved over the next several months. Here, we report this rare and interesting case for educational purposes because such a case has never been previously reported in Korea.

We investigated dietary effects of prickly pear cactus (Opuntina ficus-indica) on plasma lipids, platelet aggregation (PA), hemolysis, plasma TBARS and liver enzymes. Twenty eight volunteer diving women in Jeju island had daily 20 g cactus tea containing 27% prickly pear cactus (PPC) powder for 4 weeks, and data for the study subjects were analyzed, on the basis of diagnostic criteria for blood pressure (BP)(> or = 140/90 mmHg), plasma cholesterol (> or = 200 mg/dL) and triglyceride (> or = 150 mg/dL). The subjects with higher BP had higher plasma total cholesterol (TC) and triglyceride (TG) concentrations than those with normal BP. Those with higher TC also had higher TG. Subjects with normal BP or normal TC had higher initial slope of PA than their higher counterpart in BP and TC. PPC intake decreased plasma TG in those with higher BP. PPC intake significantly decreased the elevated initial slope in groups with normal BP, TC, and TG. Hemolysis after PPC intake decreased significantly in all the subjects and plasma TBARS decreased in the subjects with higher plasma TC and higher TG. Glutamic-oxaloacetic transaminase (GOT) significantly increased and total bilirubin significantly decreased in all the subjects after PPC intake. The present study with diving women showed that beneficial effects of short term intake of prickly pear cactus might differ depending on the subject conditions in term of blood pressure, and plasma lipids. However, long term usage of prickly pear cactus may provide preventive effects of cardiovascular diseases to all the population, presumably by hypolipidemic, antithrombotic, and antioxidant actions of its bioactive flavonoids and soluble fiber.

The present study was designed to evaluate the therapeutic potential of bioactive compounds from chloroform extract of the leaves of Hylocereus undatus in the formation of advanced glycation end products (AGEs) in vitro. Bioactivity-guided fractionation of chloroform extract from Hylocereus undatus afforded two novel 12-ursen-type triterpenes, 3β, 16α, 23-trihydroxy-urs-12- en-28-oic acid (1) and 3β, 6β, 19α, 22α-tetrahydroxy-urs-12-en-28-oic acid (2), as well as four known triterpenes 2α, 3β, 23-tetrahydroxy-urs-11-en-28-oic acid (3), 3β-acetoxy-28-hydroxyolean-12-ene (4), 3β, 16α-dihidroxyolean-12-ene (5) and 3β-acetoxy-olean-12-ene (6). Our results revealed that triterpenes 1-3 were able to inhibit the formation of AGEs in all tested assays. The data indicated that the triterpenes had inhibitory activity at the múltiple stages of glycation and that there might be a high potential for decreasing protein oxidation and protein glycation that can enhance glycative stress in diabetic complications.

OBJECTIVETo study the effects of two kinds of cactus polysaccharide on erythrocyte immune function in S180 mice.

METHODClassical pharmaceutical method and test kit.

RESULTThe cactus polysaccharide increased the content of RBC-CaR, RFER, decreased the content of RFIR, raised the content of sialic acid. And the effect of median dose group of medical cactus polysaccharide and high dose group of edible cactus polysaccharide is very remarkable (P < 0.01) compared with model group.

CONCLUSIONThe cactus polysaccharide improved the erythrocyte function of tumor-mice, which may be one of anti-tumor mechanisms.
