The following examples are sad but true tales of the journey through experimentation and torture. Ms. Eufame MacAlyane of Castle Hill Edinburg who, in 1591, was burned alive by order of the ruler of Scotland, King James I, who was an early opponent of “pain free labor”. Her “unforgivable offense” was to seek pain relief during labor [1]. Mrs. Kae Seishu volunteered as the brave first human subject to test “Tsusensan”, an oral anesthetic mixture formulated by her husband Dr. Seishu Hanaoka. The product met great success but she became permanently blind, presumably from repeated experimentation [2]. Their husbands’ agony and anguish is unimaginable! As such, it was a personalized, immeasurable, and unsharable experience. Apropos is a quote from an Urdu poet! Unknown remained their beloveds’ graves, Their nameless, traceless sanctuary. -

INTRODUCTION The method was fully validated for the determination of aconitine from whole blood samples and applied in two cases of fatal poisoning. Plants of the genus Aconitum L (family of Ranunculaceae) are known to be among the most toxic plants of the Northern Hemisphere and are widespread across Europe, Northern Asia and North America. Two plants from this genus are of particular importance: the blue-blooded Aconitum napellus L. (monkshood) which is cultivated as an ornamental plant in Europe and the yellow-blooded Aconitum vulparia Reich. (wolfsbane) which is commonly used in Asian herbal medicine1 (Figure 1). Many of the traditional Asian medicine preparations utilise both the aconite tubers and their processed products for their pharmaceutical properties, which include anti-inflammatory, analgesic and cardio- Figure 1: Aconitum napellus (monkshood) (A) and tonic effects2-4.

He was a 14 th century physician. No information is available on his birth and death – only “Al-Mughni”, a book, has been left to make him famous in surgical and medical knowledge. Methods: We used desk and historical research methods in this research, with a historical approach. This commonly used research method in human sciences was used to criticize and study the birthplace and works of Sadid al-Din Kazeroni. Results and Conclusion: Sadid al-Din Kazeroni discussed the exact issues in the field of anatomy, surgery, and gynecology. He was fluent in pharmacology. In his pharmacology book, for the first time, he named drugs considered necessary before and after surgery. In this study, we reviewed the biography and introduction of the works and reviewed “Al-Mughni”, a book on breast cancer.

Dioscorides De Materia Medica Pdf
Dioscorides de materia medica pdf Continue Herbal written in Greek Discorides in the first century This article is about the book Dioscorides. For body medical knowledge, see Materia Medica. De materia medica Cover of an early printed version of De materia medica. Lyon, 1554AuthorPediaus Dioscorides Strange plants RomeSubjectMedicinal, DrugsPublication date50-70 (50-70)Pages5 volumesTextDe materia medica in Wikisource De materia medica (Latin name for Greek work Περὶ ὕλης ἰατρικῆς, Peri hul's iatrik's, both means about medical material) is a pharmacopeia of medicinal plants and medicines that can be obtained from them. The five-volume work was written between 50 and 70 CE by Pedanius Dioscorides, a Greek physician in the Roman army. It was widely read for more than 1,500 years until it supplanted the revised herbs during the Renaissance, making it one of the longest of all natural history books. The paper describes many drugs that are known to be effective, including aconite, aloe, coloxinth, colocum, genban, opium and squirt. In all, about 600 plants are covered, along with some animals and minerals, and about 1000 medicines of them. De materia medica was distributed as illustrated manuscripts, copied by hand, in Greek, Latin and Arabic throughout the media period. From the sixteenth century, the text of the Dioscopide was translated into Italian, German, Spanish and French, and in 1655 into English. It formed the basis of herbs in these languages by such people as Leonhart Fuchs, Valery Cordus, Lobelius, Rembert Dodoens, Carolus Klusius, John Gerard and William Turner. Gradually these herbs included more and more direct observations, complementing and eventually displacing the classic text. -

CHEM 263 Notes Sep 27, 2016 Aromatic Compounds Continued Aromaticity Equivalent resonance forms gives stability to a compound. Br Br Br resonance Br Br Br 1,2-dibromobenzene Aromatic compounds are especially stable. For benzene, the delocalization energy (stability) is 36 kcal/mol relative to that expected for cyclohexatriene. To be aromatic (have aromaticity): 1. The molecule is cyclic. 2. The molecule is fully conjugated. 3. The molecule is planar. 4. The molecule contains 4n+2 π electrons, where n = 0, 1, 2, 3 … Benzene fulfills all the above criteria. It is conjugated (has three pairs of alternating double and single bonds), it is cyclic and planar, and it has 6 π electrons (where n = 1). Cyclobutadiene This molecule is cyclic, apparently fully conjugated, and planar. How many π electrons does it have? Answer: 4 Is this molecule aromatic? Answer: No. It does not fit the 4n+2 rule. Cyclooctatetraene Is this molecule aromatic? Answer: No. It has 8 π electrons, so it does not fit with 4n+2 rule In addition, cyclooctatetraene does not adopt a planar conformation. It is actually tub- shaped. In planar cyclooctatetraene, there is some angle and torsional strain. The angle in regular flat octagon is 135°, far from the optimum sp2 value of 120°, hence the tub shape. cis-trans isomerization does not occur in this molecule, and the trans isomer shown below does not exist because there is too much strain (can’t have trans double bond in small rings). Cyclodecapentaene H H This molecule has 10 π electrons. It fits with 4n+2 rule (n = 2). -
Aconite Poisoning
Version 2.0 Aconitine Poisoning 24/05/2017 Overview C19-diterpenoid alkaloids incl aconitine, mesaconitine, and hypaconitine found in plants of Aconitum species, e.g. A. napellus (wolfsbane, monkshood). Content in roots and root tubers > flowers > leaves and stems. Used in trad Chinese Medicines (chuanwu, caowu & fuz) for analgesic, indigestion, agitation, anti-inflammatory & many other purposes). Should be processed (heating & hydrolysis) to reduce aconite content (by 65-90%) before use, but may not occur. Toxic mechanism Aconite alkaloids bind with high affinity to the open state of the voltage-sensitive sodium channels at site 2, blocking their inactivation. Thus continuing sodium influx and sustained depolarization, the sodium channels become refractory to excitation. In heart, Na + influx into the cytosol, increases intracellular Ca 2+ , via Na +-Ca 2+ exchange system -> positive inotropy and induces triggered activity/ectopics. Also has anticholinergic effects mediated by blocking the vagus. Neurotoxicity: Central autonomic control - activation of the ventromedial nucleus of the hypothalamus -> hypotension and bradycardia. Peripherally – persistent voltage-sensitive sodium channel activation leads to a block with decreasing ACh quanta released. Toxicokinetics Rapid absorption from GI (onset of symptoms 10-120min). Also absorbed easily through skin. Metab: Hydrolysis with esterases and demethylation by CYP450 (esp CYP3A) enzymes to much less toxic compounds. Elim: Urine, bile & faeces. Cleared from blood <24hr, but may be detectable in urine for a week. Clinical features Neurological: sensory (paraesthesia and numbness of the face, perioral area, and the four limbs), motor (muscle weakness in the four limbs), or both. Cardiovascular: ↓BP, palpitations, chest pain, ↓HR, sinus tachycardia, ventricular ectopics, VT, TdP, VF, and junctional rhythm. -
