Title: Review on Bioactive Potential of Indonesian Forest Essential Oils Authors: Anwar, Yelfi; Pasaribu, Gunawan; M. Nazari V, M. Nazari V Abstract: Essential oils are composed of some natural, volatile, as well as aromatic compounds extracted from plants. In recent years, several studies have shown that some of their benefits can be attributed to their antimicrobial, antioxidant, anti-inflammatory, and also immunomodulatory properties. So, essential oils have been proposed as a common elective to anti-microbials or for utilize in combination with other antimicrobials against multidrug-resistant microscopic organisms. Most of the potential data about essential oils were obtained with in vitro and in vivo studies. Several types of essential oils are available in Indonesia which are reported to have biological activity such as antioxidants and antiaging are essential oils of pine (Pinus merkusii), kilemo (Litsea cubeba), agarwood (Aquilaria spp), eucalyptus (Eucalyptus citriodora), and cinnamon (Cinnamomum burmanii). The major chemical compound of pine oil is alpha pinene. Kilemo oil contains geranial. chemical marker compound of agarwood is chromone and sesquiterpenes. Eucalyptus contains citronella. The chemical component of cinnamon oil is cinnamaldehyde. Some essential oils have shown remarkable antioxidant activities when used at specific concentrations which can be due to their richness in phenolic compounds. However, toxicological studies are needed before any recommendation for application can be given. Preformulating and formulation studies will be needed to develop suitable dosage forms in order to introduce optimized pharmaceuticals (high active, low toxic) as alternative of current pharmaceutical dosage forms Key words: Pharmaceutics, Bioactivity, Chemical compound, Essential oil, Indonesian forest

The Ethanolic Extract of Rhinachantus nasutus (L.) Kurz Flower has Antioxidant, Anti-Gout, and Antibacterial Potential

Title: The Ethanolic Extract of Rhinachantus nasutus (L.) Kurz Flower has Antioxidant, Anti-Gout, and Antibacterial Potential Authors: Irawan, Candra; Elya, Berna; Hanafi, Muhammad; Chany Saputri, Fadlina Abstract: The goal of this research was to explore the potential of Rhinachantus nasutus (L.) Kurz (RnLK) flower extract as an antioxidant utilizing the ferric reducing antioxidant power (FRAP) method; the possibility that it might be used as a treatment for gout by employing the 2,4,6-tribromo-3-hydroxybenzoic acid (TBHBA) technique, as well as the possibility that it could be used as an antibacterial agent against E. coli and B. subtilis. Results: The IC50 value for the extract's ability to serve as an antioxidant is 8.62±0.006 mg/L, indicating that it is quite effective. In addition, the extract of ethanol possesses highly potent anti-gout properties, being capable of bringing about a 81.95±0.1% reduction in uric acid levels. In spite of this, the antibacterial properties of E. coli as well as B. subtilis bacteria were not particularly robust. Conclusion: The RnLK flower has the potential to produce alternative chemicals with the ability to reduce blood uric acid levels, but according to the results of the test, the antibacterial activity has little impact on E. coli and B. subtilis.

Parathyroid Carcinoma Mimicking Multiple Myeloma: A Tale of Refractory Hypercalcemia

Title: Parathyroid Carcinoma Mimicking Multiple Myeloma: A Tale of Refractory Hypercalcemia Authors: Jonatan, Christian; Wibisono, Sony Abstract: Primary hyperparathyroidism yields various symptoms, including hypercalcemia, pathological fracture, and renal impairment. Parathyroid carcinoma is the rarest cause of primary hyperparathyroidism, accounting for <1% of the cases. We reported a case of a 46-year-old male with closed fractures at the humerus and femur. Further findings revealed severe refractory hypercalcemia, renal impairment, anemia, and bone lytic lesion (CRAB). No palpable cervical mass was identified. Surprisingly, the serum protein electrophoresis was normal, and urinary Bence-Jones protein was negative along with normal bone marrow aspiration. Hence, multiple myeloma was unlikely. The intact parathyroid hormone level was very high, along with a suspicious nodule on the left thyroid lobe (TIRADS 4). Total thyroidectomy and total parathyroidectomy were performed. The post-surgical pathological examination confirmed the diagnosis of parathyroid carcinoma. After the surgery, the patient was in stable condition with normal intact parathyroid hormone and serum calcium levels. In this case, primary hyperparathyroidism was caused by parathyroid carcinoma with “CRAB” symptoms, mimicking multiple myeloma. Primary hyperparathyroidism should be considered in the patient with refractory hypercalcemia.

Ameliorative Effects of Moringa (Moringa Oleifera Lam.) Leaves Extract on Lead-Induced Oxidative Stress, Hepcidin and δ-Alad Levels in Rat’s Blood

Title: Ameliorative Effects of Moringa (Moringa Oleifera Lam.) Leaves Extract on Lead-Induced Oxidative Stress, Hepcidin and δ-Alad Levels in Rat’s Blood Authors: Saprasetya Dwi Laksana, Agung; Notopuro, Harianto; Mustika, Arifa Abstract: Introduction: Lead (Pb) is a toxic heavy metal that cause a lot health problem. Blood, especially hemoglobin and erythrocyte, is the main target of lead poisoning. Literatures explain that moringa has phytochemical contents to reduce heavy metal poisoning. This study aimed to examine ameliorative effects of moringa leaves extract on oxidative stress, hepcidin increasement and δ-alad level decline induced by lead poisoning in the blood of rat model. Methods: This study was completely randomized posttest-control group design. Forty-eight males Rattus norvegicus Wistar strain rat were divided into 4 groups. The control group or G0 (given Pb orally doses of 750 mg/kgBW/day for 7 days and was not given 50% ethanol extract of moringa leaves/MLEE). Three treatment groups (G1, G2 and G3), all were given Pb at a dose of 750 mg/kgBW/day orally for 7 days, followed by administration of MLEE for 14 days at a dose of 250 mg/kgBW/day, 500 mg/kgBW/day and 1,000 mg/kg/day orally, respectively. Blood samples were taken one day after 14 days of MLEE treatment. Pb levels was examined by AAS and δ-ALAD levels, GSH levels, MDA levels and hepcidin levels examined by ELISA. Results: MLEE doses 1,000 mg/kgBW/day for 14 days increased δ-ALAD levels, GSH levels, hepcidin levels and reduce MDA levels significantly compared to the control group. Conclusion: Moringa leaves ameliorate lead-induced poisoning by reducing oxidative stress, declining hepcidin, and increasing δ-ALAD in the blood of male Rattus norvegicus Wistar strains rats. Moringa leaves is beneficial to address Pb poisoning in the blood through antioxidants, anti-inflammation, and improving δ-ALAD level in the blood of Wistar strain rats.
