Curcumin adalah satu rempah tradisional yang mempunyai potensi untuk menyembuhkan pelbagai jenis penyakit inflamatori, termasuk artritis. Kajian ini dijalankan untuk memerhatikan kesan-kesan curcumin ke atas perubahan histopatologi dan aras interleukin-1β (IL-1β) di dalam artritis aruhan kolagen (CIA). Tiga puluh ekor tikus jantan Sprague-Dawley (150+50 g) dibahagikan kepada lima kumpulan secara rawak. Satu kumpulan dijadikan kumpulan kawalan normal (CTRL), manakala selebihnya disuntik dengan 150 μg emulsi kolagen secara subkutan pada hari 0. Kumpulan CTRL dan CIA-Curcumin-d0 masing-masing diberi suplimentasi harian minyak zaitun oil (1 ml/kg) dan curcumin (110 mg/ml/ kg) bermula pada hari 0. Kumpulan CIA-OV (kawalan negatif), CIA-Beta dan CIA-Curcumin-d14 pula, masing-masing diberi suplimentasi harian minyak zaitun (1 ml/kg), Betamethasone (0.5 mg/ml/kg), dan curcumin (110 mg/ml/kg) bermula pada hari 14. Suplimentasi harian tersebut diberi kepada tikus-tikus sehingga hari ke 42. Kajian ini menunjukkan bahawa kumpulan CIA-Beta (**P=0.00) dan CIA-Curcumin-d0 (**P=0.01) masing-masing mempamerkan purata skor histologi yang lebih rendah secara signifikan berbanding kumpulan CIA-OV. Aras IL-1β di dalam serum untuk kumpulan CIA-Beta dan CIA-Curcumin-d0 tidak meningkat secara signifikan pada hari ke 42 berbanding hari 0. Purata peningkatan aras IL-1β dari hari 0 ke hari 42 juga adalah rendah secara signifikan (**P≤0.01) untuk semua kumpulan CIA berbanding kumpulan CIA-OV. Tidak terdapat perbezaan yang signifikan dalan purata skor histologi dan aras IL-1β kumpulan of CIA-Curcumin-d0 berbanding kumpulan CIA-Beta. Kesimpulannya suplimentasi awal curcumin berpotensi untuk meminimakan perubahan yang disebabkan penyakit artritis aruhan kolagen pada tikus.
The occurrence of severe lead (Pb) poisoning has risen in certain countries.
There is increasing evidence that chronic lead exposure disturbs the prooxidant:
antioxidant balance in the brain tissue and alters brain histology. The present
study observed the antioxidant effect of tocotrienol-rich fraction (TRF) on brain
tissues of the experimental rats following lead poisoning. Eighteen (n=18) male
Sprague-Dawley rats, 6-weeks old, were randomly divided into control (CTRL)
group and experimental groups; fed with 0.2% w/v lead acetate, as PB2 group;
and fed with 0.2% w/v lead acetate and daily TRF supplementation (200 mg/kg
body weight) as PB2T group. The experiment was conducted for 30 days. At the
end of the study, the brain tissues were harvested and histopathological changes of
the hippocampal region were observed. Biochemical findings such as brain lead,
TRF and malondialdehyde (MDA) levels, and erythrocyte superoxide dismutase
(SOD) activity were determined. It was observed that atypical apoptotic-like and
disorganized neurons were present in the hippocampal region of the untreated
PB2 group compared to PB2T group. Biochemical parameters showed a significant
decrease (p < 0.05) in brain lead level in PB2T compared to PB. Even though no
significant difference (p > 0.05) was obtained for MDA level, there was a significant
increase (p < 0.05) in the erythrocyte SOD activity in PB2T compared to PB2 and
CTRL. Supplementation with TRF improved histopathological changes in the brain
tissues caused by lead exposure in drinking water by reducing lead accumulation
in the brain of experimental rats.
Curcuma longa (CL) or turmeric is an Ayurvedic herb that has been traditionally used to treat inflammatory conditions like rheumatoid arthritis (RA). Collagen-induced arthritis (CIA) is a well established experimental auto-immune mediated polyarthritis in susceptible strains of rodents. The main aim of the study was to observe the inflammatory, macroscopic and radiological changes in the arthritic ankle joints of experimentally collagen-induced arthritis animals treated with or without CL extract.
The right and left lobes of the thyroid gland are connected by an isthmus. The isthmus lies at the level of the second and third tracheal rings. Occasionaly, the isthmus may be absent. We hereby, report the absence of isthmus in a 52-year-old male cadaver of unknown origin. Both the right and left lobes were normal but they were separated. Both the right and left lobes of the thyroid gland measured 4.3 cm vertically. The separation distance between right and left glands was noted at the upper, middle and lower parts. The upper end of medial border of both lobes were separated by a distance of 1 cm while the separation distance was 0.7 cm and 1.5 cm at the middle and lower parts, respectively. The anatomical and clinical significance of absence of isthmus is important for medical personnel and the surgeons operating on the thyroid gland. The present case report is a an attempt to highlight such.
It has been a regular practice to repeatedly heat the cooking oil and consume it without knowing the harmful effects of such. The procedure to use repeatedly heated cooking oil is aimed to curb the cost of expenses. Heating results is the formation of free reactive oxygen species (ROS) which is responsible for the oxidative stress and damage to various organs in the body. The present review article discusses the harmful events occurring due to consumption of repeated heating of edible oil. A strong message is aimed to generate public awareness of the deleterious effects of consumption of heated edible oil which may help in curbing hypertension and atherosclerosis.
