Abstract

The growth of tumors is caused by imbalances between the rates at which cells are produced through cell division and the rate at which they die through a natural cell death process known as programmed cell death (also referred to as apoptosis). Problems in apoptosis mechanisms also contribute to therapy resistance, making tumors more difficult to kill with radiation or chemotherapy. It is important therefore to understand why tumors become refractory to apoptosis and to devise strategies for restoring proper function to cell death pathways in tumor cells. Recently it has been discovered that cyclooxygenase-2 (COX-2) have a relationship with apoptosis pathway. Higher levels of COX-2 have been reported in some kinds of cancer. One of the roles of COX-2 in tumor development is its positive effect on the survival of tumor cells. The goal of this project is to provide review insights into the role of COX-2 in cancer. We will explore whether COX-2 inhibitors can shut off survival genes in cancer cells, and we will study how COX-2 affects the programmed cell death machinery of cancer cells. Understanding the mechanisms by which COX-2 contributes to cancer development will reveal to what extent this enzyme is an important target in the chemoprevention and treatment of cancer.

Abstract

Neuropathic pain resulted from injury to nerves is often resistant to current treatments and can seriously cause chronic pain if no appropriate treatment is given. This study was designed to prove the effectiveness of gabapentin and baclofen in increasing latency time toward thermal stimulus and recovering the morphology of dorsal horn of spinal cord in neuropathic-induced chronic pain. Forty mice were divided into 8 groups i.e sham, negative control, gabapentin at three different doses (10, 30, 100 nmol) and baclofen at three different doses (1, 10, 30 nmol). Neuropathic condition was induced by ligation of sciatic nerve with Partial Sciatic Nerve Ligation (PSNL) method. Gabapentin and baclofen were administrated intrathecally once a day for seven days, a week after neuropathic induction. Latency time toward thermal stimulus was measured on days 0, 1, 3, 5, 7, 8, 10, 12 and 14 after induction. Histology of the dorsal horn of spinal cord tissue was examined by haematoxylline-eosin staining. The results showed that intrathecal injection of gabapentin and baclofen significantly increased latency time of mice toward thermal stimulus compared with negative control. Gabapentin and baclofen are effective as treatment for neuropathic pain. They can also help the recovery process of the histology in dorsal horn in neuropathic pain.Keywords: Baclofen, dorsal horn, gabapentin, neuropathic pain, PSNLEfek Gabapentin dan Baclofen terhadap Studi Histologi pada Nyeri NeuropatiNyeri neuropati berasal dari luka pada saraf yang umumnya sulit diterapi sehingga menyebabkan nyeri kronik bila tanpa managemen terapi yang tepat. Tujuan penelitian ini adalah membuktikan efektivitas gabapentin dan baclofen dalam meningkatkan waktu ketahanan terhadap panas dan memperbaiki morfologi dorsal horn dari spinal cord pada keadaan nyeri kronik yang disebabkan neuropati.

Abstract

ABSTRACTCelery (Apium graveolens L.) is one of plants that initially only used for cooking. Based onthe research by Wolski, et al., 2002, celery contains chemical compound such as tannins andpolyphenols. Tannins may be useful as an anti-diarrheal because of the adstringent effect. Thisstudy aims to determine the antidiarrheals activity of celery leaf in male mice strain Balb-C that wasinduced by castor oil. The ethanolic extract of celery leaves divided into three dose group (5,10 and20 mg/kgBW). This research was done by two methods, protection of castor oil induced diarrheaand intestinal transit. After five hours treatment, frequency of defecation, number of soft/liquidfeses and weight of stools were calculated. The gastrointestinal transit rate was expressed as thepercentage of longest distance traversed by the charcoal divided by the total length of the smallintestine.From the protection of castor oil induced diarrhea method, ethanol extract of celery 20mg/20gBW doses decrease frequency of defecation, quantity of the soft / liquid stool and weight ofstool after 5 hours treatment in male mice that had been induced by castor oil. The effectiveness ofethanol extract 20mg/20gBW dose equivalent to loperamid 0.06mg/20gBW (one way anova test atthe α = 95%). Besides, the ethanol extract of celery can prolong intestinal transit of mice, but lowerthan loperamid 0.06mg/20g (one-way anova test at the α = 95%).Keywords: antidiarrheal, castor oil, celery, intestinal transit, taninns

Abstract

Inflammation is the body's reaction to infection, irritation, or foreign substances, as an effort to defend the body's defenses. Inflammatory mediators such as bradykinin, prostaglandins, fluid extravasation, and tissue damage are essential to protect our body as an inflammatory response. One of the plants in Indonesia which is the potential to develop is Cinnamomum burmanii. These plants are identified to contain some substances such as flavonoid, tannin, and saponin. This study was aimed to determine the anti-inflammatory effect of the Cinnamomum burmanii extract using in vitro method compared with diclofenac sodium. Cinnamon bark was extracted using 96% of ethanol, and phytochemical screening was determined. Anti-inflammatory test in vitro using two methods, membrane stabilization using red blood cell suspension and protein denaturation inhibition using bovine serum albumin. After an anti-inflammatory test using the membrane stabilization method, the IC50 of the extract was 84.45 ± 3.55 g/mL, while in the protein denaturation method, the IC50 of the extract was 57.412 ± 0.718µg/mL. Even though the IC50 of the extract was lower, it is still higher than diclofenac sodium as drug control. Our result showed that cinnamon has potential as an antiinflammation and needs to develop further

Abstract

ABSTRACTPainful diabetic neuropathy (PDN) is a complication of long-term Diabetes Mellitus (DM) characterized by hyperalgesia and allodynia. In streptozotocin (STZ)-induced diabetic mice, higher dose of STZ and lengthen hiperglycemic condition results in better model of PDN. However, higher dose of STZ tend to induce mortality. Evaluate the doses of STZ that caused PDN with less mortality rate and the timing of pain behavior development in mice model of PDN. Balb/c mice were divided into non-diabetic and STZ-induced diabetic group. The doses of STZ were started from 180 mg/kg i.p. Serum glucose levels were measured 7 days after induction. Mice with glucose levels ≥ 200 mg/dl were considered as diabetic. Pain behaviour was determined by four method i.e. hot plate, tail flick test, von Frey fillament and Randall Selitto,measured on week-0 (baseline), 1, 2, 3, 4 and 5. Data were presented as mean±SEM. The mean differences between weeks were evaluated by One-Way ANOVA and the mean differences between two groups by independent t-test. STZ doses 180 mg/kg, 150 mg/kg and 120 mg/kg caused 100% death and STZ 90 mg/kg failed to induce diabetic condition. STZ 110 mg/kg resulted in 0% mortality while it induced diabetes in 100% mice. Latency time toward thermal stimulus decreased to 5.8 s at 1st week after the mice become diabetes  (p<0.05) and it was continued decrease until 4th week. The same result was also showed in tail flick test and Randal Selitto. The pain sensitivity determined by von Frey filament decreased to 1.37 g at week 1 (p<0.05) and continued decrease until 5th week. Optimum dose of STZ to induce PDN was 110 mg/kg. Pain behaviour of diabetic group was observed at 1st week after diabetic and continued until 4th week.Keywords: PDN, hot plate, tail flick test, von Frey fillament, Randall Selitto
